Sperm Whale

 

The Biggest Animals Kingdom and in The World | Sperm Whale | The sperm whale is the largest toothed whale with adult males of up to 20.5 meters (67 feet) in length and weighing up to 57,000 kg (56 ton long, 63 short tons). In contrast, the second largest toothed whale peak Baird measured 12.8 meters (42 feet) and weigh up to 15 short tons (14,000 kg). The Nantucket Whaling Museum is about 5.5 meters (18 feet) in length of the mandible. The museum claims the individual was 80 feet (24 m) long, the whale that sank the Essex (one of the incidents behind Moby-Dick) claimed that about 85 feet (26 m). Today, people are usually not more than 18.3 meters (60 feet) long and 51 000 kg (50 long tons; 56 short tons) in weight says another view that the exploitation by overwhaling almost no effect on the size of the bull sperm whales, and the size may actually have increased in modern times, on the basis of the density-dependent effects And "one of the sexually dimorfisch of all cetaceans. At birth both sexes are almost the same size, but adult males are usually 30% to 50% longer and three times larger than females Single body of the sperm whale is unlikely to be confused with other species

The sperm whale flukes are triangular and very thick. The whale light its wing begins high above the water as the immersion nutrition. In contrast to the smooth skin of most large whales back skin folds and usually compared to a passing whale watching enthusiasts. The sperm whale has a lower encephalization quotient many other whale and dolphin species, lower than monkeys and much lower than in humans.  Sperm whale is the largest brain of all mammals, both in absolute and relative terms. The olfactory system is reduced, suggesting that the sperm whale has a poor sense of smell and taste. The pyramidal tract is underdeveloped, reducing the limbs The sperm whale is one of the most cosmopolitan species. Preferably ice-free waters over 1000 meters (3300 feet) deep, although both sexes by the temperate and tropical oceans and seas, only adult males populate higher latitudes.

Tickets low for both the Black Sea and the Red Sea can be used to explain their absence., the lower layers are also Black Sea anoxic and contains high concentrations of sulfur compounds such as hydrogen sulfide. Coastal areas with significant sperm whale populations include the Azores and the Caribbean island of Dominica. Sexually mature females give birth once every 4-20 years (pregnancy rate at the time of whaling). Like other whales, whale milk has a higher fat content than terrestrial mammals approximately 36%, compared with 4% in cow's milk. Has an energy content of about 3840 kcal / kg (16,070 kJ / kg), compared with only 640 kcal / kg (2700 kJ / kg) in cow's milk. Suckling calves of women who are not their mother. Males reach sexual maturity at the age of 18. After reaching sexual maturity, males move to higher latitudes where the water is colder and feeding is more productive. Women remain at lower latitudes. A 2008 study published in the journal Current Biology, shows evidence that whales can sleep with both sides of the brain. It seems that some whales around 7 percent of the time, most of the time between 06:00 and midnight clock fall into a deep sleep.

Orca

 

The Biggest Animals Kingdom and in The World | Orca | A typical orca clearly a black background, white chest and sides, and a white patch above and behind the eye. It has a heavy body and sturdy with a large dorsal fin up to 2 meters (6.6 feet) in height. Behind the fin, gray "saddle patch" dark in the back. Antarctic killer whales may pale gray to nearly white backs. When viewed from a distance, the young man with other cetacean species such as the false killer whale or Risso's dolphins confused. The killer whale's teeth are very strong and enamel. Inclined teeth and appearance so the killer whale to withstand severe shocks prey, while the middle and back teeth stay firmly in place. Orcas are the largest members of the dolphin family. Men usually 6-8 meters (20-26 feet) in length and weigh more than 6 tons (5.9 long tons; 6.6 short tons). [53] The females are smaller, usually 5-7 meters (16-23 feet) and a weight of about 3.4 tons (3.0 to 3.9 long tons, from 3.3 to 4.4 tons shortlist) . The largest male orca in history was 9.8 m (32 ft), weighing about 10 tonnes (9.8 long tons 11 short tons), while the largest female was 8.5 meters (28 feet) and weighs 7.5 tons (8.3 long tons 7.4 short tons). The murderess delphinid whale skeleton structure is typical, but it is strong.

Killer whale pectoral fins are large and round, similar to rowing. Males have significantly larger pectoral fins than females. Men and women have different patterns of black and white leather in their genitals. Gender differences were also evident in the skull and jaw are adult men and women and has a large occipital crest. A single orca are often by their dorsal fin and saddle patch. Published lists contain identifying photographs and names for hundreds of North Pacific animals. Photo identification has enabled the population of killer whales is more than estimated and has great insight into the life and social structures of each year. White whale, but in normal killer whales were sighted in the Bering Sea and around St. Lawrence Island, and near the Russian coast rare sporadic. In February 2008, a white whale has two miles (3.2 km) of Kanaga Volcano photographed in the Aleutian Islands. Killer whales have good eyesight above and below the water, excellent hearing and a good sense of touch. Orcas mature woman in nearly 15 years. Killer whales are unique among whales because their heads are smaller than parent. Females breed until the age of 40, which will raise five children on average.

Life expectancy in captivity of killer whales are usually much shorter, usually less than 25 years, but many people live in 30 years, and some reached the age of 40 ° In many cases, the life of the animal murderess dependent. Killer whales are found in all oceans and most seas. Systematic surveys indicate the highest densities of killer whales (> 0:40 individuals per 100 km ²) in the north-east Atlantic from the coast of Norway, in the North Pacific along the Aleutian Islands, Gulf of Alaska and the Southern Ocean off the coast of Antarctica. High density has also been reported but not quantified in the western North Pacific around the Sea of Japan, Sea of Okhotsk, Kuril Islands, Kamchatka and the Commander Islands and in the southern hemisphere off the coast of South Australia, Patagonia, the southern coast of Brazil and the southern end. Information sharing by the sea and tropical waters is weak, but the sightings spread, but not often that the killer whale can survive in most water temperatures. With the decline of the Arctic sea ice rapidly in the Hudson Strait, their range now extends deep into the northwest Atlantic.

Migration patterns are poorly understood. Each summer, the same people along the coast of British Columbia and Washington. Transient pods noted from southern Alaska to central California. Resident orca pod areas ranging from 320 to 1.300 km (200-810 miles). Occasionally, killer whales swim into freshwater rivers. Documented with the Columbia River in the United States 100 miles (160 km).

Right Whale

 

The Biggest Animals Kingdom and in The World | Right Whale | Unlike other whales, whales have distinctive callosities (rough patches of skin) in the head, with broad shoulders, no dorsal fin, sometimes with a white belly and jaw of a long face and curved, or higher, which begins above the eye . Corns appear white due to large colonies cyamids (whale lice). Right whales can grow to 18 m (59 ft) long and weigh up to 100 short tons (91 t, 89 long tons), considerably larger than humpbacks or gray, but smaller than the blues. Whales swim slowly, reaching only 5 knots (9.3 km / h) at a higher speed. During the mating season, which can occur at any time of the North Atlantic whales congregate in "active surface" groups with a maximum of 20 men who associate with a woman. The males are not aggressive towards other males and humpback whales. The average age of first birth in the North Atlantic whales is estimated to be between 7.5 and 9. Females breed every 3-4 years.

The right whale grows rapidly in the first year, usually doubling the length. Little is known about the life of whales. One of the few well-documented cases is that of a female North Atlantic whale was photographed with a child in 1935, then photographed in 1959, 1980, 1985 and 1992. In other whiskers, which feed by filtering the water from the dam. The whale then expels the water, with their beards to the dam to maintain. Right whales "three major predators are humans, whales and sharks. When danger lurks, a group of whales can be grouped in a circle and hit highlighting the tail.

The three Eubalaena species inhabit three different regions of the world the North Atlantic Ocean in the west by the Atlantic Ocean, the Pacific Ocean in a band from Japan to Alaska and all areas of the Southern Ocean. Whales can only handle the moderate temperatures between 20 and 60 degrees latitude. The Basques were the first to commercially hunt whales, beginning as early as the 11th century in the Bay of Biscay. The Basque coastal whaling continued sporadically in the 19th century.

"Yankee Whalers' new colonies replace the Basques. For 1750, commercial whaling in the North Atlantic was pretty much over. The whaling station in the south of Brazil was founded in 1796, in Imbituba. During the following century, whaling in the Southern Yankee diffusion and the Pacific, where the Americans united fleets from different European countries. As highlighted stocks are low, the world banned commercial whaling in 1937 right. Madeira has his last two whales in 1968. Japan has 23 Pacific whales in 1940 and more under scientific permit in 1960.

The southern right whale, Hermanus, South Africa is one of the world centers for whale watching. During the winter months (July-October), Southern Right whales come so close to the coast, visitors can watch the whales from the hotel in a strategic location. The city has a "whale crier" (cf. town crier) to walk to town announcing where whales are seen. Southern right whales can also be seen in other winter breeding grounds. In Brazil Imbituba, Santa Catarina is recognized as the whale national capital and has annual celebrations Right Whale week in September, when mothers and calves often. The old whaling station has become a museum dedicated to the whales. In winter in Argentina, Península Valdés in Patagonia is home to the largest population of the propagation of the species, with more than 2,000 animals cataloged by the Whale Conservation Institute and Ocean Alliance.

Blue Whale

 

The Biggest Animals Kingdom and in The World | Blue Whale | The blue whale has a long tapered body appears elongated compared with other whales building muscle. If the surface to breathe, the blue whale raises its shoulder and blowhole water to a greater extent than other large whales such as fin and sei whales. Some blue whales in the North Atlantic and North Pacific raise flukes when diving. When breathing, the whale has a spectacular peak vertical column of up to 12 meters (39 feet), usually 9 meters (30 feet). Blue whales have designed two holes for a stir. Fins are 3-4 feet (9.8 to 13 feet) long. Blue whales can reach speeds of 50 kilometers per hour (31 mph) over short bursts, usually in conjunction with other whales, but 20 kilometers per hour (12 mph), a typical speed. Blue whales usually alone or with another person In places where a high concentration of feed, such as blue whale 50 views spread over a small area. The blue whale is the largest animal ever known to have lived.

Blue whales weigh because of their size. As is the case with most of the great white whale whalers, adult blue whales have never weighed a whole, but divided into manageable pieces first. That more than 180 tons (200 short tons) The largest blue whale accurately weighed by NMML scientists to date a woman weighs 177 tons (195 short tons). As a whole whales, blue in the North Atlantic and the Pacific appear to be smaller than the average for sub-Antarctic waters. The largest whale ever weighed 190 tons (210 short tons). The longest whales ever recorded were two females measuring 33.6 m (110 ft) and 33.3 m (109 ft), although in neither case gathered.

The weight fragmentary whales longer NMML scientists measured was 29.9 meters (98 feet), a woman caught by Japanese whalers in the Antarctic in 1946-47. Quentin R. Walsh, USCG, and functions as a whaling factory ship of Ulysses inspector checks the extent of about 30 m (98 ft) of pregnant blue whales in Antarctica in the 1937-1938 season captured. Reported longer reported in the North Pacific was 27.1 meters (89 feet) of women taken by Japanese whalers in 1959, and the longest in the North Atlantic, was 28.1 meters (92 feet) in the Davis Strait surprised woman.

Because of its size different organs of the blue whale is the largest in the animal kingdom. A blue whale's tongue weighs around 2.7 tons (3.0 short tons) and when fully developed, the mouth is big enough for up to 90 tons (99 short tons) of food and water. A blue whale's aorta is about 23 cm (9.1 inches) in diameter. In the first seven months of his life, a blue whale calf drinks approximately 400 liters (100 gallons) of milk per day. Blue whale calves gain weight quickly, up to 90 kg (200 pounds) for 24 hours. Blue whales have relatively small brains, only 15.25 pounds (6.91 kilograms), about 0.007% of body weight.

Blue whales feed almost exclusively on krill, but also have a small amount of copepods. The species of this zooplankton eaten by blue whales varies from ocean to ocean. In the North Atlantic Meganyctiphanes Norvegica, Thysanoessa raschii, Thysanoessa inermis and Thysanoessa longicaudata food are normal in the North Pacific simplex, Euphausia pacifica, Thysanoessa inermis, Thysanoessa longipes, Thysanoessa spinifera, and Megalops Nyctiphanes Nematoscelis and in Antarctica., Euphausia superba, Euphausia crystallorophias and Valentini Euphausia An adult blue whale can eat up to 40 million krill in a day. The daily requirement of an adult blue whale is in the region of 1.5 million kilocalories.

Because as krill, blue whales feed mainly at a depth of over 100 meters (330 feet) during the day and feed on the surface at night. The longest recorded 36th minute immersion whale jump is fed forward krill groups, animals, and a large amount of water in the mouth. The blue whale also incidentally consumes small fish, crustaceans and squid caught krill. The calf weighs about 2.5 tons (2.8 short tons), and is about 7 meters (23 feet) in length. Blue whale calves drink 380-570 liters (100-150 gallons) of milk per day. In studies of North Pacific blue whales photogrammetric adults have shown an average of 21.6 m (71 ft), with a maximum of more than 24.4 m (80 feet), although the female 26.5 m near Pescadero , California (87 feet) of 1979 stranded.

Scientists estimate that blue whales can live for at least 80 years, as each record date is not in the era of whales is not known with certainty for many years. Whales only natural predator is the Orca. Studies show that up to 25% of adult blue whales scars resulting from orca attacks. Blue whale strandings are extremely rare, and as a result of the social class structure, "mass strandings are unknown. In 1920, a blue whale washed ashore near Bragar on the Isle of Lewis in the Outer Hebrides of Scotland. Since the introduction of the ban on whaling studies have not examined the conservation of the world's population depends on blue whale is increasing or stable. The IUCN Red List has the blue whale as "endangered", as it has since the creation of the list. The largest known concentration, consisting of approximately 2,800 people is the northeast Pacific population of northern blue whale (B. m. Musculus) subspecies that ranges from Alaska to Costa Rica, but mostly seen from California in summer.

Apart from Iceland, blue whales have been spotted as far north as Spitsbergen and Jan Mayen, though such sightings are rare. Scientists do not know where these whales spend their winters. The total population of the North Atlantic estimated between 600 and 1500. In the southern hemisphere, apparently two distinct subspecies, B. m. intermediate, the Antarctic blue whale, and little studied pygmy blue whale, B. m. brevicauda in the waters of the Indian Ocean. Recent studies (mid-1998), an estimate of 2,280 blue whales in the Antarctic (where less than 1% are probably pygmy blue whales). For example, pygmy blue whales in the northern Indian Ocean (Oman, Maldives and Sri Lanka), where it forms a distinct population also included, the population of blue whales Chile and Peru also a significant population. Some Antarctic blue whales approach the eastern South Atlantic coast in winter, and occasionally, their sounds from Peru, Western Australia, and the northern Indian Ocean. Efforts towards the blue whale population by calculating marine mammologists be maintained at Duke University, the Ocean Biogeographic Information System Spatial Analysis Megavertebrate ecological populations (Figure OBIS), supported by a collection of marine mammal sighting data about 130 sources

A young blue whale skeleton in the New Bedford Whaling Museum in New Bedford, Massachusetts installed. The Aquarium of the Pacific in Long Beach, California, has hung a life-size model of a blue whale mother and her calf from the ceiling of the great hall. A true blue whale skeleton in the Canadian Museum of Nature in Ottawa, opened in May 2010. The Natural History Museum in Gothenburg, Sweden contains the only stuffed blue whale in the world. The Melbourne Museum has a skeleton of the pygmy blue whale.
