Crocodile

  
The Biggest Animals Kingdom and in The World | Crocodile | Crocodiles are among the most biologically complex reptiles despite their prehistoric look. The physical characteristics of a crocodile make you a thief to be successful. Its aerodynamic body enables it to swim faster. Webbed feet are an advantage in shallower water where the animal is moving sometimes on foot. Crocodiles have a tab palatal a rigid tissue at the back of the mouth, which blocks the penetration of water. Like other archosaurs are diapsid crocodile, although the post-temporal fenestrae are reduced. Crocodilian scales have assumed that pores in sensory function, similarly to the fishing line side. Crocodiles are very fast over short distances, even out of the water. 


The bite pressure crocodile is more than 5000 psi (30,000 kPa), compared to only 335 psi (2300 kPa) for a rottweiler, 400 pounds (2800 kPa) square inch of a large shark white, 800 psi (6000 kPa) to 1,000 psi (7000 kPa) for a hyena, or 2000 psi (10,000 kPa) for a large alligator, the jaws are opened, but a set very weak muscles. Crocodiles can thus be used to study or recording transport holding jaws or mandibles with their major bands of rubber tubes inside of cars, even damped closed. Herodotus claimed Nile crocodiles had a symbiotic relationship with certain birds, such as the Egyptian Plover which give mouth of the crocodile and get leeches feed on the blood of a crocodile, with no evidence of this interaction actually occurs in some species of crocodiles, it is very likely mythical or fictional allegorical. Many large crocodiles swallow stones (called gastroliths or stomach stones) that can serve as ballast to balance your body, or assist in grinding the food for birds like to bite.


Crocodiles can produce sounds during distress and in aggressive displays.  Crocodiles eat fish, birds, mammals and occasionally smaller crocodiles. Crocodiles are protected in many parts of the world, but they are also grown commercially. Their skins are tanned and used as leather shoes and handbags, crocodile meat is also considered a delicacy. The most cultivated species are salt and Nile crocodiles, while a hybrid of the Saltwater and the rare Siamese crocodile is also created on farms in Asia. Crocodiles are more closely related to birds and dinosaurs than to most animals classified as reptiles used to have three in the group Archosauria ("ruling reptiles"). Crocodile embryos do not have sex chromosomes, and in contrast to humans, sex is not genetically determined. Crocodiles may have a form of instinct. 


The land speed record for a crocodile is 17 km / h (11 mph) on a galloping freshwater crocodiles in Australia measured. The maximum speed varies from species to species. Certain species can gallop, including Cuban crocodiles, New Guinea crocodiles, African dwarf crocodiles and even smaller Nile crocodiles. Crocodiles can reach speeds of 10 or 11 km / h (about 7 miles per hour) when they "belly run", and often faster if the river slipping muddy. Crocodiles do not have sweat glands and let heat through the mouth. The BBC-TV you reported the Nile crocodile that lurked a long time underwater to catch prey is built a large oxygen debt.


Size varies greatly between species, from the dwarf crocodile to the saltwater crocodile. Types and Osteolaemus Palaeosuchus grow (4.9 feet) for an adult size of only 1 m (3.3 ft) to 1.5 m. Larger species can most 4.85 meters (15.9 feet) long and weigh well reach more than 1,200 kg (2,600 lb). Crocodiles have sexual dimorphism, with males much larger and growing faster than females. Despite their large adult crocodiles start their life around 20 centimeters (7.9 inches) long. The largest species of crocodile is the saltwater crocodile in eastern India, northern Australia, Southeast Asia and in the surrounding waters. Two major certifiable records are both 6.2 meters (20 ft) crocodile. 


If the second crocodile skin that was actually was measured by Jerome zoologist Montague, and skins as are known to underestimate the actual size of the animal, it is possible that this crocodile was at least another 10 cm in length. The largest crocodile ever be kept in captivity is an Estuarine Siamese hybrid named Yai (Thai: ใหญ่, meaning big) (born June 10, 1972) at the famous Samut prakarn Crocodile Farm and Zoo, Thailand. This animal is 6 meters (19.69 feet) (19 ft 8 in) long and weighing 1114.27 kg. The crocodile was shot near Dhamara in 1926 and later its skull was preserved by the king after Kanika. Experts estimate the crocodile animal was 20 feet (6.1 m) to 23 feet (7.0 meters) in length, as was the size of the skull, 1/9 of the length of the body measured.


Measuring crocodile age is not reliable, although several techniques are used to derive a reasonable estimate. One of the oldest crocodiles recorded died in a zoo in Russia. A freshwater crocodile male at Australia Zoo is estimated to be 130 years old. As a result of the shooting was this crocodile (known affectionately as "Mr. Freshy" called) lost his right eye. Crocodiles have a smooth skin on the belly and sides, while the dorsal surfaces are armored with large osteoderms.

Komodo Dragon

  
The Biggest Animals Kingdom and in The World | Komodo Dragon | The Komodo dragon is also known as the Komodo Monitor or the Komodo Island monitor in scientific literature, although this is not very often. The Komodo dragon is believed to be differentiated from its Australian ancestors 4 million years ago. However, the fossil evidence recently that the Komodo dragon Queensland developed in Australia for the first time in Indonesia. Drastic reductions in sea level during the last glaciation discovered long stretches of the continental shelf that the Komodo dragon climbed populated and isolated island in its current range compared to the level of the sea below. In nature, an adult Komodo dragon usually weighs about 70 kilograms (150 pounds), although captive specimens often weigh more. The largest verified wild specimen was 3.13 meters (10 ft 3 in) long and weighed 166 kg (370 lb), including undigested food. The Komodo dragon has a long tail like his body, as well as about 60 frequently replaced serrated teeth capable of measuring up to 2.5 cm (1 inch) in length. 


The Komodo dragon prefers hot and dry places, and usually lives in dry open grasslands, savannas and rainforests at low altitude. Komodo dragons are solitary, coming together only to breed and eat. The prey, the capture is out of reach, the Komodo dragon may stand on its hind legs using its tail as a prop. As the Komodo dragon matures, its claws are used primarily as a weapon, such as large size makes climbing impractical. For accommodation, the Komodo dragon digs holes of 1-3 meters (3-10 feet) wide, with its powerful claws capable of measuring and front legs. Females are antagonistic and resist with their claws and teeth in the early stages of courtship. Other courtship between men scratched his chin on the female, hard scratches on his back, and licking.

Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards to be. The female lays its eggs in caves dug into a hillside or deserted nest in the hills of Orange-footed Scrubfowl (a moundbuilder or megapode), with a preference for the desolate hills. Clutches contain an average of 20 eggs have an incubation period of 7-8 months. Young Komodo dragons spend much of their early life in the trees where they are relatively safe from predators, including cannibalistic adults, the young dragon to take 10% of their diet. Komodo dragons about three to five years to mature and can live up to 50 years The Komodo dragon is an endangered species and IUCN Red List, there are approximately 4,000 to 5,000 Komodo dragons live in the wild found.

 

Their populations are on islands Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1700) and Flores (perhaps 2,000) limit. However, there are concerns that there are currently only 350 breeding females allay these concerns, the Komodo National Park was established in 1980 to protect the Komodo dragon populations on islands such as Komodo, Rinca and Padar. Later, the Wae Wuul Wolo Tado and reserves were opened on Flores, the Komodo dragon to help with conservation.


Komodo dragons, to avoid encounters with humans. The older animals will retreat even from people from a shorter distance. While there are stories of unprovoked attack Komodo dragons or hunt for people, most of these reports or not caused by bites or serious defensive. The volcanic activity, earthquakes, loss of habitat, fire, loss of prey due to poaching, tourism and illegal poaching of these dragons have contributed to the state of emergency Komodo dragon. On Padar, a former resident of the Komodo Dragon was extinct, the last of which individuals were observed in 1975.

Rhinoceros



The Biggest Animals Kingdom and in The World | Rhinoceros | Rhinoceros, often abbreviated as rhino, is a group of five extant species of knee-less, odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to southern Asia. The horns are made of keratin, the same type of protein that makes up hair and fingernails. Both African species and the Sumatran rhinoceros have two horns, while the Indian and Javan rhinoceros have a single horn.


The word rhinoceros is derived through Latin from the Ancient Greek, which is composed  (rhino-, "nose") and κέρας (keras, "horn"). The plural in English is rhinoceros or rhinoceroses. The collective noun for a group of rhinoceroses is crash or herd. The five living species fall into three categories. The two African species, the white rhinoceros and the black rhinoceros, diverged during the early Pliocene (about 5 million years ago) but the Dicerotini group to which they belong originated in the middle Miocene, about 14.2 million years ago. The main difference between black and white rhinos is the shape of their mouths.
 
White rhinos have broad flat lips for grazing and black rhinos have long pointed lips for eating foliage White rhinoceros are divided into northern and southern subspecies. There are two living Rhinocerotini species, the Indian rhinoceros and the Javan rhinoceros, which diverged from one another about 10 million years ago.  Interspecific hybridisation of black and white rhinoceros has also been confirmed

Kinds Of Rhino :

White rhinoceros
Black rhinoceros
Indian rhinoceros
Javan rhinoceros
Sumatran rhinoceros



This small hornless ancestor resembled a tapir or small horse more than a rhino. The smallest hyracodontids were dog-sized; the largest was Indricotherium, believed to be one of the largest land mammals that ever existed.  The family Amynodontidae, also known as "aquatic rhinos", dispersed across North America and Eurasia, from the late Eocene to early Oligocene.  The family of all the modern rhinoceros, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia Also known as the giant rhinoceros, Elasmotherium was two meters tall, five meters long and weighed around five tons, with a single enormous horn, hypsodont teeth and long legs for running.


Of the extant rhinoceros species, the Sumatran rhino is the most archaic, first emerging more than 15 million years ago. The Sumatran rhino was closely related to the woolly rhinoceros, but not to the other modern species. The Indian rhino and Javan rhino are closely related and from a more recent lineage of Asian rhino.

Lynx

  
The Biggest Animals Kingdom and in The World | Lynx | Lynx have short tails and tufts of black hair characteristics on the tips of their ears. All species of lynx also white fur on his chest, belly and inner legs, which are extensions of the chest and belly fur. Smaller species are lynx and lynx in Canada, while the largest is the Eurasian lynx, with considerable variation within species. Lynx are usually solitary, although a small group of lynx may travel and hunt together occasionally. The gestation period of lynx is about 70 days. Lynx will create their dens in crevices or under ledges. They also feed on a wide range of animals, deer, reindeer, deer, small deer, chamois and, for smaller, more common prey: rabbits, fish, foxes, sheep, squirrels, mice, turkeys and other birds, and goats. The Eurasian lynx is between the central and northern Europe across Asia to India. 


A resettlement project, started in 1973, was successfully reintroduced lynx in the Slovenian Alps and the Croatian region of Gorski Kotar and Velebit, including Croatia Plitvice Lakes National Park and National Park Risnjak. In both countries, the lynx is listed as an endangered species and protected by law. Various resettlement projects undertaken in 1970 lynx have been successful in different regions of Switzerland. Lynx are more common in northern Europe, especially Sweden, Estonia, Finland, and parts of northern Russia. The lynx population in Finland was 1900-2100 individuals in 2008, and the numbers have increased every year since 1992. The lynx population in Finland is currently estimated at greater than ever. 


The critically endangered Iberian Lynx lives in southern Spain and previously in the eastern part of Portugal. A lynx is expected to play outside binnder Silves in the Algarve in southern Portugal.
The lynx hunting is illegal in many countries.

Leopard

 

The Biggest Animals Kingdom and in The World | Leopard | Leopards are agile and stealthy predator. The muscles attached to scapula are exceptionally strong, which increase their ability to climb trees. Males are about 30% larger than females, weighing 30-91 kg (66-200 lbs), compared to 23 to 60 kg (51 to 130 pounds) for females. Big men up to 91 kg (£ 200) have been documented in the Kruger National Park in South Africa, however, men of the coastal mountains of South Africa average 31 kg (68 pounds) and females of the edge of the desert in Somalia average of 23 to 27 kg (51 to 60 pounds). The smaller subspecies of leopard is usually the Arabian leopard (P. p. Nimr), the deserts of the Middle East, with the adult females of the race weighs only 17 kg (37 pounds). Other subspecies of large, in which males weigh up to 91 kg (200 £), is the Sri Lankan leopard (P. p. Kotiya) and the Anatolian leopard (P. p. Tulliana). These tend to be more leopards are found in areas that lack tigers and lions, thereby placing the leopard on top of the food chain without restriction of competition of large prey size. The largest leopards recorded weighed 96.5 kg (213 lb). 


The body of the leopard is relatively long, and their legs are short. Leopards show a great diversity of color patterns displayed and the rosette. The rosettes are circular in East Africa, but tend to be more square in southern Africa and higher in Asian populations. Leopards can sometimes be confused with two other big cats paintings, the cheetah, which can coexist with in Africa, and the jaguar, a Neotropical species that naturally coexist. However, the patterns of dots in each are different: the cheetah has simple black spots, evenly distributed, the jaguar has small spots inside the rosettes polygonal, while the leopard is usually round, rosettes smaller than the jaguar. The jaguar is more like building a leopard, but is generally larger and looks more muscular and bulky. In ancient times, a leopard was believed to be a hybrid of a lion and a panther, which is reflected in its name, which is composed of a greek λέων leon (lion) and brown πάρδος (male panther). The Greek word is related to Sanskrit पृदाकु pṛdāku (snake, tiger, panther), and probably derives from a Mediterranean language, like the Egyptian.


Black Panther refers to leopards with melanic genes, which are not infrequent in forest habitats. The generic component of its modern scientific name, Panthera pardus, derives from the Latin via Greek πάνθηρ (Panther). In sub-Saharan Africa, the species is still numerous and even thriving in marginal environments, where other large cats disappeared. But the people of North Africa may be extinct The data on its distribution in Asia are not consistent-populations of the south-west and central Asia are small and fragmented, in North-East, are in grave danger, but the Indian subcontinent, Southeast Asia and China, leopards are still relatively abundant. their number is greater than that of other species Panthera all face conservation concerns more acute. Leopards live mainly in grasslands, woodlands and riverine forests. They are usually associated with savanna and rainforest, but leopards are extremely adaptable: the Russian Far East, inhabiting the temperate forests where winter temperatures reach a minimum of -25 ° C (-13 ° F). 


The leopards are elusive, solitary and largely nocturnal. Level of activity varies depending on the type of habitat and prey that hunt. Radio tracking and analysis of feces in West Africa showed that rainforest leopards are more likely to be diurnal and crepuscular. Forest leopards are also more specialized in prey selection and exhibit seasonal differences in activity patterns. Leopards are known for their ability to climb and have been observed resting on the branches of the trees during the day, dragging their kills the trees and hang them there, and head down trees. Depending on the region, leopards may mate all year round. Young skin tends to be larger and thicker than that of adults. Leopards have been reported to reach 21 years in captivity.

Tiger

  
The Biggest Animals Kingdom | Tiger | The ancient remains of the tiger, like a cat, called Panthera palaeosinensis were found in China and Java. The earliest fossils of true tigers are known from Java, and between 1.6 and 1.8 million years. Subspecies called Trinil tiger (Panthera tigris trinilensis) lived about 1.2 million years ago and is known from fossils found at Trinil in Java. Tigers first reached India and northern Asia during the Pleistocene, reaching eastern Beringia (but not the Americas), Japan and Sakhalin. Fossils Japan show that local tigers were as subspecies island survivors, lower than the forms of the continent. Before the Holocene, tigers lived on the island of Borneo and the island of Palawan in the Philippines. Tigers have a muscular body, with a particularly powerful forelimbs and a large head. Model band is also in the skin of a tiger. If Tiger were shaved, its distinctive camouflage pattern can be saved.


Tiger is the most variable in size all the big cats, even more than the leopard, and more than lions. Bengal, Caspian Sea and Amur tiger subspecies are among the largest living cats, and are one of the largest cat that ever existed. An adult male tiger from northern India or Siberia, than the average male lion about 45 kg (99 pounds), women vary in length from 200 to 275 cm (79 to 108), weighing 65 167 kg (140,370 pounds), with a maximum length skulls 268-318 mm (10.6 to 12.5 cm). Large male Siberian tiger can reach a total length of 3.5 m (11.5 ft) "to curves", 3.3 m (10.8 ft) "between pegs" and weighing 306 kg (670 pounds). This is significantly larger than the size of the smallest of life reached the subspecies of tiger, Sumatran tigers, which reach a weight of 75 to 140 kg (170,310 pounds). The total length of the tail of the tiger is from 0.6 to 1.1 m (2.0 to 3.6 feet). In the shoulder, the Tigers could stand differently from 0.7 to 1.22 m (2.3 to 4.0 feet).


Tigress less than men in each subspecies, although the size difference between male and female tigers tends to be more pronounced in larger tiger subspecies, with males weighing up to 1.7 times more than women. In addition, male tigers have foot pads front wider than females. Biologists use this difference to determine the sex, based on a few tracks of a tiger. The skull is very similar to a tiger a lion, although the front area, as a rule, non-depressed or flat with a region slightly longer post-orbital. Only the large island inhabited by tigers today, Sumatra. Tigers have been eradicated on the island of Bali in 1940, around the Caspian Sea in 1970, and the island of Java in 1980.

Habitat loss and the constant killing of tigers and tiger prey precipitated these extirpations, a process that continues to leave forests devoid of tigers and other large mammals in South and Southeast Asia.  Fossils show that the Tigers were presented at the Borneo and Palawan in the Philippines in the late Pleistocene and Holocene. The tiger habitat is generally include adequate coverage, proximity to water, and abundance of prey. Bengal tigers live in many types of forests, including wet green, semi-evergreen of Assam and West Bengal, the mangrove forests in the delta of the Ganges, deciduous forest and thorn forests of Nepal Western Ghats. In the wild, tigers mostly feed on animals large and medium sized businesses. Sambar, gaur, chital, barasingha, wild boar, nilgai, and both the domestic buffalo and buffalo, favored victim of a tiger in India.

In Siberia, the main types are the victims of the Manchurian deer, wild boar, spotted deer, elk, deer and musk deer. In Sumatra, sambar, muntjac, wild boar, and Malayan tapir hunt. In between the first Caspian tiger, prey included Saiga antelope, camels, Caucasian bison, yak and wild horses. Adult elephants are too big to be a common prey, but conflicts between tigers and elephants also occasionally occur. The case where a tiger killed an adult Indian rhino is not observed. Tigers also sometimes attack pets such as dogs, cows, horses and donkeys. 


Tigers old or injured and are unable to capture their natural prey have become cannibals, this pattern is repeated many times throughout India. Exceptional case is that the Sundarbans, where healthy tigers prey upon fishermen and farmers in search of forest products, people, forming a small part of the diet of the tiger. Tiger will have some vegetation in dietary fiber, fruit of the tree slowly while playing a game Tigers are thought to be nocturnal predators hunt at night. When hunting large prey, tigers prefer to bite the throat and use their forepaws to hold the prey, bringing it to the ground. Tiger is still locked around his neck until the victim dies of asphyxiation. With this method, water buffalo and gaurs weighing more than a tonne have been killed by tigers more weighing approximately one-sixth.

With small prey, the tiger bites the nape, often breaking the spinal cord enters the trachea, or splitting the jugular vein or carotid artery. Litter usually consists of 3-4 cubs of about 1 kg (2.2 pounds) each, which are born blind and helpless.  Females reach sexual maturity at 3-4 years, while males reach sexual maturity in 4-5 years. During his lifetime, a woman will give birth to an equal number of tiger cubs males and females. Tigers reproduce well in captivity, captive, and the population in the United States can compete with wild populations of the world.

Giraffe

 
  
The Biggest Animals Kingdom | Giraffe | Giraffe has its first origin of the name known in the Arabic words Zarafa (زرافہ), probably some African languages. species name is the Latin word for giraffe. Giraffe is one of only two survivors of the family Giraffidae, the other the okapi. Other climate change caused the extinction of giraffes in Asia, while Africa has survived and is emitted in a number of new species. G. Giraffe appeared about 1 million years in East Africa during the Pleistocene. Some biologists believe that modern giraffes to G. find jumae G. gracilis is more likely candidate. Giraffe is one of the many species originally described by Linnaeus in 1758. He gave the name of the binomial Cervus Giraffe. Morten Thrane Brünnich classified in the genus Giraffa 1772. In the early 19th century, Jean-Baptiste Lamarck believed that the long neck of the giraffe was "acquired characteristic", developed by generations of ancestors as a giraffe trying to get to the leaves of tall trees. This theory was rejected in the end, and now scientists believe that the giraffe's neck appeared to Darwinian natural selection as the ancestors of giraffes with long necks and had a competitive advantage allowing them to better reproduce and pass their genes.


A fully grown giraffe is 5-6 meters (16-20 feet) in height, with men higher than women, the average weight is 1,600 kg (3,500 pounds) for adult males and 830 kg (1,800 pounds) for adult women. Despite its long neck and legs, the giraffe's body is relatively short. Located on both sides of the head, a big giraffe, rolling his eyes to teach him a panoramic view from a great height. Giraffes see in color, and their hearing and smell are also sharp. Prehensile tongue giraffe is about 50 cm (20 inches). The upper lip is a giraffe, a tenacious and is useful when searching for food. Each person has a unique giraffe fur. Leather Giraffe mostly gray. Along the animal's neck is a mane of short erect hairs. Giraffes usually inhabit savannas, grasslands and woodlands. Angolan Giraffe can be found in the desert environment. Giraffes browse on the twigs of trees, preferring trees of genera Acacia, Commiphora and Terminalia, which are an important source of calcium and protein to sustain growth rates of the giraffe. 


The giraffe eats about 34 kilograms (75 pounds) of leaves daily.When said that giraffes can chew the bark of twigs. Although grazing animals, the giraffe is known to visit the carcass and lick the dry bones of the meat. During the rainy season, food is abundant and giraffes are more common, while during the dry season, they gather around the evergreen trees and shrubs remain. In ruminant animals, giraffes chew food and then swallow for processing and then passes the half-digested much neck and back gum in his mouth to chew again. The giraffe requires less food than many other herbivores, because they eat the leaves of a higher concentration of nutrients and has a digestive system more efficient animal faeces in the form of small granules. It is common for a giraffe in the saliva during feeding. Giraffes are likely to have common goals for hunters from all over Africa. Tail hair flyswatters, bracelets, necklaces and wire. Smoke from the burning giraffe skin was used in the Buganda traditional healers for the treatment of bleeding from the nose. Habitat destruction affected the giraffe, too: in the Sahel, the need for firewood and grazing land for cattle room led to deforestation. 


In 1997, Jonathan Kingdon has suggested that the Nubian giraffe was the most endangered of all the giraffes in 2010, he can count at least 250, but this estimate is uncertain. Private game reserves have helped to save the population of giraffes in South Africa. Giraffe Manor in Nairobi, a popular hotel, which also serves as a sanctuary for Rothschild giraffes. The giraffe is a protected species in most of its range. 


Platypus

 
  
The Biggest Animals Kingdom | Platypus | The body and the broad, flat tail of the platypus are equipped with thick fur and brown covers to keep the traps of an insulating layer of air, the animal warm. The coat is waterproof, and the texture is similar to that of a platypus with its tail mole.The storage of fat reserves (an adaptation in animals like the Tasmanian Devil, and fat-tailed sheep found). The strap is greater on the front and back legs when walking on the ground, unlike bird's beak (in which separate the top and bottom to reveal the mouth), the snout of the Platypus is a sensory organ, the mouth of the folded bottom. Weight varies considerably, from 0.7 to 2.4 kg (1.5 to 5.3 lb), larger in males than in females: males average 50 cm (20 inches) total length while females average 43 cm (17 inches). The platypus has an average body temperature of about 32 ° C (90 ° F) instead of 37 ° C (99 ° F), typical of placental mammals. Research suggests that it was a gradual adaptation to harsh environmental conditions from the few surviving species of monotremes, rather than a historical characteristic of monotremes.


Modern Platypus young have three-pointed molars which they lose before or shortly after leaving the breeding burrow; have Adults keratinized massive blocks in their place. Platypus jaw is constructed differently from those of other mammals, and the muscle of the jaw opening is different. The platypus has extra bones in the shoulder girdle, including an interclavicle, which is not found in other mammals. The office of the platypus electric front is the most sensitive of all monotremes. Receptors in the electric lines in the skin of the rostrocaudal arranged ticket, while mechanoreceptors (tactile sensing) are evenly distributed over the bill. Both electroreceptors and mechanoreceptors in the bill dominate the somatotopic map of the platypus brain, in the same way human hands dominate the Penfield homunculus map.The Platypus can determine the direction of an electric source, perhaps by comparing differences in signal strength on the sheet of electroreceptors. 


The convergence of inputs and tactile cortical electrosensory that a mechanism for determining the distance of prey to move when encountered two electrical signals and mechanical pressure pulses, the difference between arrival times of the calculation into two signals is capable of enabling the distance. The platypus feeds either by sight or smell, and closed his eyes, ears, nose, and each time he dives. Experiments have shown that the Platypus will even react to an "artificial shrimp" if a small electrical current is passed through. The platypus is semi-aquatic, living in small streams and rivers on a wide range of highlands of Tasmania and the Australian Alps to the rainforests of coastal Queensland as far north as the base of Cape York Peninsula.

 In captivity, platypuses have lived up to 17 years, and wild specimens that were recovered while 11 years. Natural enemies are snakes, water rats, lizards, hawks, owls and eagles. Low Platypus numbers in northern Australia are possibly due to the looting by crocodiles.  The platypus is an excellent swimmer and spends much time in the water in search of food. When swimming, it can be distinguished from other Australian mammals by the absence of visible ears. Unique among mammals, hanging out with a swim in a rowing motion alternating the two front feet, although all four feet webbed feet platypus supporting the hind legs (which is held against the body), not to advance, but are used for steering in combination with the tail.

The species is endothermic, maintaining their body temperature at 32 ° C (90 ° F), lower than most mammals, even when foraging for hours in water below 5 ° C (41 ° F). The platypus is a carnivore: it feeds on annelid worms and insects, freshwater shrimp, larvae and Yabbies (freshwater crayfish) that it digs on the riverbed with its snout or catches while swimming. The platypus needs to eat about 20% of their weight every day, he is averaging 12 hours per day expenditures for food needs. When he is not in the water, the platypus a short, straight off the construction of an oval cross-section in retirement, almost always in the bank, not far from the water level, and often hidden under a protective tangle of roots.


When the platypus was first encountered by European naturalists, they were about whether the female laid eggs divided. Recognizing the high cost of wiring England by word, Caldwell famous, but tersely wired London, "laying monotremes, the egg meroblastic." In other words, lay eggs, monotremes, and eggs are similar to those of reptiles in the only part of the egg cell divides, how it develops. The species is a breeding season, mating occurs between June and October, although some local variation occurs between populations over its frequency range. Historical observation, mark-recapture studies and preliminary investigations of population genetics indicate the possibility of both resident and members of the population, and suggest a polygynous system.

Outside the breeding season of the platypus lives buried in a single floor, the entrance is about 30 cm (12 inches) above the water table. The female platypus has a pair of ovaries but only the left is functional It sets 1-3 (usually two) small leathery eggs (similar to those of reptiles), about 11 mm (0.43 in.) in diameter and slightly rounder than bird eggs. The yolk is absorbed by the developing young. During the second phase, the numbers and development, in the final stages, the egg tooth. The newly hatched young are vulnerable, blind, hairless, and are fed by breast milk. Although the mammary glands, the Platypus lacks teats. During incubation and weaning, the mother leaves the den for short periods at first, to seek food.

Eagle

 

The Biggest Animals Kingdom | Eagle | Eagles are large birds of prey strongly built, with a heavy head and beak. Even the smallest eagles, like the Booted Eagle (which is like a hawk Red-tailed Hawk or common), have a relatively long wings and wide and even more direct flight, faster. Most eagles are larger than any other raptors apart from some vultures. Species as the Eagles are in the order named from the South Nicobar Serpent Eagle, 450 g (1 lb) to 40 cm (16 inches), for 6.7 kg (14.7 lbs) Steller Sea Eagle and 100 cm (39 in. ) Philippine Eagle. Like all birds of prey, eagles have very large curved beaks for tearing flesh from their prey, strong, muscular legs and claws. The female of all kinds of known Eagle are greater than the core. Eagles usually build their nests, called eyries, in tall trees or on cliffs. 


Below the eagle are among the largest birds of prey are just some of the condors and vultures of the Old World are larger. Four species of Steller Sea Eagle East Asia, the harpy eagle of South and Central America, the Philippine Eagle and Wedge-tailed Eagle of Australia reached one meter in length. The Wedge-tailed hawk and eagle are also shorter, measuring 89-100 cm and 80-104 cm. Steller Sea Eagle is generally between 85 to 94 cm in 33 to 37).

Zebras in the Old World horses in recent years has developed 4,000,000. Grevy's zebras (and maybe even mountain zebras) are with donkeys and asses on a separate line from other lines zebras. This means that both striped horses has developed more than once, or that the common ancestor of zebra striped zebras and donkeys were kept and only the strip. The animals had stocky zebra-like bodies and short, narrow, donkey-like skull. The Hagerman horse is also called the American zebra or Hagerman zebra. Grevy's zebra is much higher, while the mountain zebra is something smallerIt thought that animals were zebras white with black stripes, and some zebras have white bellies.


The "zebra crossing" is the name of black and white stripes of zebras. A variety of hypotheses considered responsible for the development of distinctive stripes of zebras were proposed. The first vertical stripes can contribute to the zebra skin on the grass. According Another hypothesis is that since the animals in the herd of zebra, the stripes may help to confuse predators, a number of zebras standing or moving may appear closely together as a large animal, making it difficult for the lion to choose any single zebra to attack. Like horses, zebras walk, trot, trot and canter. When chased, a zebra will zig-zag back and forth, making it difficult for thieves. When cornered the zebra rebel and kick or bite her attacker.

Mountain zebras and Plains zebras live in groups known as "harem", consisting of one stallion with up to six mares and their foals. Unlike the other zebra species, Grevy's zebras do not have permanent social bonds. A group of these zebras rarely stays together for more than a few months. Like the other two species, zebra, zebras are organizing a bachelor males in groups. Like horses, zebras sleep standing up, and only sleep when neighbors are around to warn them of predators. Grevy's zebras make mule-like Bray. The zebra ears signify its mood. If the zebra is tense in a calm and friendly, or upright ears.

A zebra foal is brown and white instead of black and white birth. Plains and Mountain zebra foals are protected by their mothers as well as the head stallion and other mares in their group. Grevy's zebra foals have only their mother as a protector regularly because, as mentioned above, Grevy's zebra groups often dissolve after a few months. Attempts have been made to train zebras to assemble since they have greater resistance to diseases of the African horse. In England, the zoological collector Lord Rothschild frequently used zebras to drag a car. In 1907, Rosendo Ribeiro used, the first doctor in Nairobi, Kenya, a riding zebra for house calls. aptain Horace Hayes, in comparison with "Points of the Horse" (circa 1893), the usefulness of different species of zebra.
