Chicken

 

The Biggest Animals Kingdom and in The World | Chicken | Chickens are omnivores. More old world chicken, a hen, died of a heart attack at 16 years old, according to the Guinness Book of Records. Roosters can usually be differentiated from hens by their striking plumage of long flowing tails and shiny feathers, neck edge (IRE) and value (saddle) which are typically bright and vibrant colors than females of the same species. However, in some breeds, such as the Sebright, the rooster is slightly pointed neck feathers, the same color as the hen. Adult chickens have a fleshy crest on their heads called a comb or cockscomb, and hanging flaps of skin on each side with their beaks called wattles. The sleeve or beard is a mutation found in several breeds of chickens that causes blur on the face of extra chicken, giving the appearance of a beard.

Chickens may occasionally fly briefly to explore their surroundings, but generally do so only to flee perceived danger. Chickens are gregarious birds and live in groups. Individual chickens in a flock dominate others, establishing a "pecking order", with dominant individuals have priority of access to food and nesting sites. Adding chickens and a flock of birds exists can lead to violence and injuries. Chickens try to put in nests that already contain eggs, and have been known to move eggs from nests on their own neighbors. If the nest is small, or determined from chickens in particular, this can lead to chickens that attempt to put each other. Roosters crowing (a loud, sharp sometimes called) is a territorial signal to other roosters. Hens cluck loudly after laying an egg, and also to call their chicks. Chickens also give a "warning call" when they think bass see an approaching predator.

John Fallon, the overseer of the project, stated that chickens have maintained the ability to make teeth, under certain conditions When a rooster finds food, he may call other chickens to eat first. To start dating, some roosters may dance in a circle around or near a hen ("a circle dance"), often lowering his wing closest to the hen. The dance triggers a response in the female brain, and when the hen responds to his "call", the rooster may mount the hen and proceed with the fertilization. Chickens raised for eggs are called laying hens. Some breeds of hens can produce over 300 eggs per year, "the highest rate of oviposition is 371 real eggs in 364 days. In the UK and Europe, laying hens are then slaughtered and used in processed foods, or sold as "chicken soup.

In 2000, there were 50.4 million tonnes of eggs produced in the world (executive guide to trends in birds in the world, 2001) and an estimated 53.4 million tons of table eggs were produced in 2002. During 2009, approximately 62.1 million tons of eggs were produced worldwide by a herd of about 6,400 stalls million chickens. Chicken eggs are widely used in many types of dishes, both sweet and savory, like many roasts. Eggs can be scrambled, fried, baked, boiled, pickled, and poached. The egg white, or egg white protein, but contains little or no fat, and can be used for cooking separately from the yolk. Hens do not need a man to produce eggs, fertilize only. A batch containing only women continue to produce eggs, but the eggs will all be sterile.

Some people find the behavior of chickens fun and educational. An unusual variety of chicken that has its origins in South America is the araucana, bred in southern Chile by Mapuche people. In 2007, an international team of researchers published the results of analysis of chicken bones found on the Arauco Peninsula in south central Chile. Radiocarbon dating suggested that the chickens were Pre-Columbian, and DNA analysis showed that they were related to prehistoric populations of chickens in Polynesia. These results seem to confirm that the chickens came from Polynesia and that there were transpacific contacts between Polynesia and South America before Columbus's arrival to America. Modeling of the potential marine carbon contribution to the Chilean archaeological specimen casts further doubt on claims for pre-Columbian chickens, and definitive proof will require further analyzes of ancient DNA sequences and radiocarbon and stable isotope data from archaeological excavations Chile and Polynesia

Crane

 

The Biggest Animals Kingdom and in The World | Crane | Cranes are large for large birds like bird that flies highest in the world. They vary in size Demoiselle Crane, which measures 90 cm (35 inches) in length, Saro crane that can reach up to 176 cm (69 in), although heavier Manchurian crane, which can weigh 12 kg (26 lb) prior to migration. The plumage of the cranes varies by habitat. Species that inhabit large open wetlands tend to have more white in the plumage that species inhabiting wetlands minors or forest habitats, which tend to be more gray. These species are also generally white larger. The small size and color of forest species is thought to help maintain a less conspicuous profile while nesting, two of these species (common and Sandhill Cranes) also daub their feathers with mud skins during nesting. Most species of cranes are some areas of bare skin on the face, the only two exceptions are the Blue Crane and Demoiselle.

In the two crown cranes trachea is shorter and slightly impressed only the sternal bone, trachea while the other species is longer and penetrates into the breastbone. Asia is the center of crane diversity, with eight species, followed by Africa, with five species of resident and wintering populations sixth. Australia, Europe and North America have two species. There are four types of cranes, two, Balearica (two species) and Bugeranus (more or less) are totally limited in Africa, and the third has a completely Anthropoides African species and the species found in Africa, Asia and Europe. Most species of cranes depend on wetlands and require large tracts of open space. Most species of cranes nest in shallow wetlands.

The two species of cranes Anthropoides that nest and feed in pastures (or arid grasslands or deserts) require wetlands to roost at night. The only two species that do not always land on wetlands are the two African crowned cranes (Balearica), which are the only crane that sleep in trees.  Some species have both sedentary and migratory populations. The cranes are diurnal birds vary in their sociability to the season. During the breeding season are territorial and tend to remain in its territory all the time. Unlike the non-breeding season tend to be gregarious, forming large flocks to rest, socialize and feed in some species. The crane as a family consumes a wide range of foodstuffs, animal ranging from vegetable matter. Among the wide range of products consumed some models, species shorter sales usually feed on dry highlands, while the highest turnover of species feed in wetlands.

Crane foraging use different techniques for different food types. If more than one species of cranes exist in one location, each kind separate niches adopt, in order to minimize competition and niche overlap. In a major lake in Jiangxi Province in China, Siberian cranes and mudlfats feed in shallow water, the black-necked crane at the edge of wetlands, sedge meadows hooded crane and the last two species also feed on farmland, along with the common crane Cranes are perennially monogamous breeders, establish long-term pair bonds that can last the life of the birds. In a study of Sandhill Cranes in Florida, seven of the 22 pairs studied remained together for a period of 11 years. Cranes are territorial and seasonal breeders in general.

Seasonally varies between and within species, depending on local conditions. Migratory species start breeding to reach their spawning summer, between April and June. The breeding season of tropical species, however, usually coincides with the rainy or monsoon. Territory size also varies depending on the position. In contrast to the red-crowned crane territories may require 500 hectares, and couples can defend even larger territories than that, up to several thousand hectares.

Chimpanzee

 

The Biggest Animals Kingdom and in The World | Chimpanzee | The genus Pan is Considered to be part of the subfamily are Homininae Also part of the human being. These two species are the closest living evolutionary relatives to humans, sharing a common ancestor with humans 4-6000000 years. Common chimpanzee lung arms outstretched with a duration of one and a half times longer than the height of the body and the arms of a chimpanzee are longer than the legs. Chimpanzee feet are better suited for walking than Those of the orangutan chimp Because The soles are wider and shorter fingers. Both the common chimpanzee and bonobo can walk upright on two legs When carrying objects With their hands and arms. The Bonobo has proportionately higher limbs and Tends to walk upright Often more than the normal chimpanzee. A University of Chicago Medical Centre study has found significant genetic differences between chimpanzee populations.

The Common Chimpanzee has an omnivorous diet, a troop hunting culture based on beta males led by an alpha male, and highly complex social relationships. Different groups of chimpanzees Also have different cultural behavior with preferences for types of tools. The Common Chimpanzee has a tendency to show higher levels of aggression than the Bonobo. The average sleep time of a captive chimpanzee is 9.7 hours per day. Common chimpanzees are universally ADOPTED, like all monkeys, unable-to-swim. Chimpanzees live in large social groups with multiple males and females mentions verschillende communities.

Chimpanzees live in a leaner hierarchy in All which more than one person may be enough to dominate other members of lower rank to dominate. Normally a dominant male Referred to as the alpha male. The alpha male is the highest man who controls the group and maintains order in a dispute. In chimpanzee society the 'dominant male' is not always the biggest and strongest guy but more or Manipulative man and politician who can influence events Within a group. Male chimpanzees Typically achieve dominance through cultivating allies That person to support in case of future ambitions for power. This serves to intimidate other members in an attempt to stay in power and maintain authority, and can be Crucial for the alpha male is to Maintain Their status. Lower-ranking chimpanzees will show respect by making submissive gestures in body language or reaching Their hands, while growling. Female chimpanzees Shown deference to alpha male by presenting Their hind legs.

Female chimpanzees Also have a hierarchy which is Influenced by the position of a female individual within a group. In some chimpanzee communities, the young women may inherit high status from a high-ranking mother. The females will form Also allies or lower rank women dominate. Unlike the men, a main purpose of acquiring dominant status for access to mating privileges and sometimes violent domination of subordinates women to Acquire dominant status for access to resources zoals food. High-ranking females Often get first access to resources. In general, both genders Acquire dominant status, social status Within a group to improve.

Often it is the women who choose the alpha male. For a male chimpanzee to win the alpha state, you need the acceptance of women in the community. In some cases, a group of women who have a dominant alpha male is not Their preference and rather back up the other guy who see the potential to lead the group as a successful alpha male.

Brain research has Shown chimp chimp communication activates an area of the brains of chimpanzees in the same position as Broca's area, a language center in the human brain from November 2007 Approximately 1,300 chimpanzees were housed in 10 U.S. laboratories (3000 great apes in captivity there), either wild-caught, or acquired from circuses, animal trainers, or zoos. Most labs either conduct or chimpanzees invasive research, defined as "inoculation with an infectious agent, surgery or biopsy Conducted for the sake of research and not Because Of chimpanzees and / or drug testing. 'Two Federally funded laboratories use chimps: Yerkes National Primate Research Laboratory at Emory University in Atlanta, Georgia, and the Southwest National Primate Center in San Antonio, Texas. Some individual chimps currently in U.S. laboratories Experiments for about 40 years.

With the publication of the chimpanzee genome, planning the use of chimpanzees in laboratories reportedly Increasing far, with some scientists argue That the federal moratorium on breeding chimps for research Should be lifted.

Lobster

 

The Biggest Animals Kingdom and in The World | Lobster | Lobsters are invertebrates with a hard protective layer of exoskeleton. Like most arthropods must molt lobster to grow, making them vulnerable. Lobsters have 10 walking legs, the front three pairs bear claws, of which the first are larger than the other. Although, like most other arthropods, lobsters are largely bilaterally symmetrical some genera possess unequal, specialized claws.  Lobster anatomy includes the cephalothorax which fuses the head and chest, covered by a shell of chitin, and abdomen. Because lobsters live in a murky environment at the bottom of the ocean, they mostly use their antennae as sensors. The lobster eye structure prior a convex reflecting retina.

Lobsters possess a green hepatopancreas, called tomalley of chefs, which functions as the animal liver and pancreas. Awards Chilenophoberidae fossil families on the pattern of grooves in the shell of the base Some research suggests that lobsters do not delay, weaken, or lose fertility with age, and that older lobsters may fertile than younger lobsters. It has been argued that lobsters can have negligible senescence and some scientists have argued, could actually live indefinitely, apart from injury, disease, capture, etc. According to Guinness World Records, the largest lobster was in Nova Scotia, Canada caught and weighed 20.15 kg (44.4 lb). Lobsters are found in all oceans.

Lobsters are omnivorous and usually eat live prey such as fish, molluscs, crustaceans, worms and some vegetables. Although lobster skin has been found in the stomachs of lobsters, it's because lobsters eat their shed skin after molting In general, lobsters 25-50 centimeters (10-20 inches) long, and move. Animal parasites of the genus Symbion, the only member of the tribe Cycliophora live exclusively on lobster gills and mouthparts. Different types of Symbion were found in the three commercially important North Atlantic lobster Nephrops norvegicus, Homarus americanus and Homarus gammarus.

Lobsters can. Lobster is in water from 1 to 500 fathoms fished (900 m 2), although some lobsters live in 2,000 fathoms (3,700 m). A lobster fisherman can lay up to 2,000 traps. Around 2000, expanding aquaculture due to overfishing and high demand, lobster. Since 2008, no lobster aquaculture operation had achieved commercial success, mainly due to the fact that lobsters eat each other (cannibalism) and the slow growth of the species, these two problems it is difficult to make profitable lobster aquaculture

Hyena

 

The Biggest Animals Kingdom and in The World | Hyena | Hyenas have relatively short torsos, and are very solid and wolf-like in construction, but a slight hindquarters, high withers and sloping shoulders their significantly down compared to their tails. Hyenas are digitigrade, with the front and hind legs with four digits each and sporting bulging pawpads. How canids, hyenas have short, blunt, non-retractable claws. With the exception of the spotted hyena, hyaenids have striped fur, probably inherited from their ancestors viverrid. Hyenas no baculum. Hyenas an extra pair of ribs canines and their rough tongues like those of cats and viverrids. Males in most hyena species are larger than females, although the spotted hyena is exceptional, because it is the female of the species that transcends and dominates the man. In addition, in contrast to other hyena external genitalia of the female spotted hyena very similar to that of the male.

The strength of the jaws is such that both striped and spotted hyena are listed on dogs kill with a bite to the neck without skin. The secretions are mainly used for marking territory, though both the aardwolf and the striped hyena will spray if they are attacked. When attacked by lions or dogs, and brown striped hyenas will feign death, although the spotted hyena will fiercely defend. The spotted hyena is very vocal, producing a variety of different sounds consisting of screams, grunts, groans, lows, giggles, cries, grunts, groans and laughter. The striped hyena is relatively quiet, the sounds limited to a chattering laugh and cry.

The link between hyenas involves a series of short links with short intervals, unlike canids, usually intervene in a process in copula. Spotted hyena cubs are born almost fully developed, with eyes open and incisors and canines erupt, while unmarked adults. In contrast, striped hyena cubs are born with adult markings, closed eyes and small ears. Hyenas not vomit food for their young male spotted hyenas and have no role in raising their puppies, even though male striped hyenas do. The striped hyena is primarily a scavenger, although sometimes attack and kill a defenseless animal can be overcome, and supplement their diet with fruit.

An aardwolf can eat 300,000 Trinervitermes a single output Spotted hyenas vary in their folkloric and mythological scenes, depending on the ethnic group from which the stories. It is often difficult to know whether spotted hyenas are the specific hyena species present in these stories, particularly in West Africa, as both spotted and striped hyenas are often given the same names. In Tanzania, there is a belief that witches use spotted hyenas as mounts. The Kaguru Tanzania and South Kujamaat Senegal view hyenas as inedible and greedy hermaphrodites. A mythical African tribe called Bouda is known that the members of the house can be transformed into hyenas. In the Near and Middle East, striped hyenas are generally regarded as physical incarnations of jinns. Arab writer Al-Quazweeni (1204-1283) spoke of a tribe of people called Al-Dabeyoun meaning "hyena people".

Al-Doumairy in his writings Hawayan Al-Koubra (1406) wrote that striped hyenas were creatures vampires who attacked people at night and sucked the blood from the neck. He also wrote that hyenas only attacked brave people. Arab folklore tells of how hyenas can victims spellbound with their eyes or sometimes with their pheromones. The image of striped hyenas in Afghanistan, India and Palestine is more varied. Though feared, striped hyenas were also a symbol of love and fertility, leading to numerous varieties of love medicine derived from hyena body parts. Among the Baluch and in northern India, witches or wizards said that striped hyenas night driving. The striped hyena is mentioned in the Bible. The Arabic word for striped hyenas, dhubba, alluded in a valley in Israel known as Shaqq-ud-Diba (meaning "cleft of the hyenas") and Wadi-Abu-Diba (meaning "valley of the hyenas").

The modern Hebrew word for hyena tzebua or zevoa, which literally means "creature of color." Under hyenas, only the spotted hyena and the stripes are known as man-eaters. Hyenas are known to have preyed on humans in prehistory: human hair is found fossil hyena dung from 257,000 years 195000 Some paleontologists believe that competition and predation by cave hyenas in Siberia was a major factor in delaying human colonization of Alaska . Hyenas may occasionally stolen human kills, or entered campsites to drag off the young and weak, just like modern spotted hyenas in Africa. The oldest human remains Alaska coincide with about the same time cave hyenas became extinct, causing some paleontologists to infer that hyena predation was what prevented humans from crossing the Bering Strait before.

Dogs used to capture human behavior can seem fat people to live to develop, hyena attacks on people in South Sudan rose during the second Sudanese civil war, when the human cadavers were available to them. Although spotted hyenas do prey on people in modern times, incidents are rare. However, according SGDRN (Sociedade para a Gestão Desenvolvimento and Reserva do Niassa Mozambique), attacks on people of spotted hyenas are likely to be underestimated. According to hyena expert Dr. Hans Kruuk, man-eating spotted hyenas are usually very large specimens: A pair of man-eating hyenas, responsible for killing 27 people in Mlanje, Malawi in 1962, were weighed at 72 kg (159 lb ) and 77 kg (170 lb) after being hit.

Victims of spotted hyenas tend to be women, children and sick or disabled men: Theodore Roosevelt wrote about the way in 1908-1909 in Uganda, spotted hyenas regular patients of African sleeping sickness slain in their sleep outside in the fields. Spotted hyenas are widely feared in Malawi, where they are known to occasionally attack people at night, especially during the hot season when people sleep outside. Hyena attacks were widely reported in a clear and Phalombe of Malawi, north of Michesi Mountain.

Under normal circumstances, striped hyenas are very shy around people, although they may exhibit bold behavior towards people overnight. In rare cases, striped hyenas preyed on humans. In 1880 a hyena reported to have attacked people, especially children, sleeping over a three year period in the Province Iğdır, with 25 children and 3 adults injured in a year. The attacks have caused local authorities announcing a reward of 100 rubles for killing each hyena. Cases are known in Azerbaijan of striped hyenas killing children sleeping in courtyards during 1930 and 1940. In 1942 a sleeping guard torn in his hut by a hyena in Golyndzhakh. The cases of children taken by hyenas at night are known in the south-east of Turkmenistan Bathyz Nature Reserve. Several attacks have occurred in India in 1962, nine children were believed to have been taken by hyenas in the town of Bhagalpur in Bihar state in a period of six weeks and 19 children under four years were killed by hyenas in Karnataka, Bihar in 1974.

Chinchilla

 

The Biggest Animals Kingdom and in The World | Chinchilla | Chinchillas are two live chinchilla chinchilla (formerly known as chinchilla brevicaudata) and Chinchilla lanigera. Domestic chinchillas are thought to come from C. lanigera speciesIn their natural habitat, chinchillas live in burrows or crevices in rocks. Chinchillas have a variety of defensive tactics including spraying urine and releasing fur if bitten. In the wild, chinchillas have been found to eat the leaves of plants, fruits, seeds and small insects. In nature, chinchillas live in social groups that resemble colonies but the correct name of the herd.

In relation to this long pregnancy, chinchillas are born fully fur and with their eyes open. International trade in chinchilla fur goes back to the 16th century. One complete chinchilla coats can take up to 150 skins, as chinchillas are relatively small. Although it is illegal to hunt wild chinchillas, the wild animals in danger of extinction due to illegal hunting going on. Chinchillas animals are still bred for this useChinchillas requires a lot of work.

Wooden sticks, pumice stone and chew toys are good options, but conifer forests and citrus fruits (like cedar or orange) should be avoided due to the high content resins, oils and phenols that are toxic for chinchillas. Birch, willow, apple tree, manzanita or dry pine forests are safe for chinchillas to chew. Chinchillas dissipate heat, directing the ears of the blood of large dimensions, the ears so red report overheating. Chinchillas can be found in different colors.

Only color found in nature is standard gray. Animals instinctively clean their fur by taking dust baths, in which rolling in special powder of fine pumice. Chinchillas do not bathe in water because the dense fur prevents air drying, retaining moisture close to the skin, which can cause the growth of fungus or rot fur. Wet chinchilla must be dried immediately with towels and hairdryer heat. Thick fur resistant parasites such as fleas, and decreases the free wool, making chinchillas hypo-allergenic

Chinchillas eat and drink in very small quantities. Mixed in the diet, chinchillas may refuse healthy fiber pellets in favor of items like raisins and seeds. Nuts should be avoided due to of its high fat content. foods that are high in protein and alfalfa hay can cause liver problems and should be limitedThe chinchilla is often used as an animal model to study the auditory system, because the range of hearing chinchillas ( 20 Hz to 30 kHz) and cochlear size is close to the man, and the chinchilla cochlea is very easy to access.

Jellyfish

 

The Biggest Animals Kingdom and in The World | Jellyfish | Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory and circulatory systems. Jellyfish bodies are composed of more than 95% water, most of their umbrella mass of gelatinous material called mesoglea jelly, which is surrounded by two layers of protective film. Jellyfish do not have a brain or central nervous system, but use a free network of nerves in the epidermis, which is called "neural network". Jellyfish detects various stimuli including the touch of other animals on the network of nerve then transmits impulses both throughout the network and the nerve to the circular nerve ring on rhopalial lapel located on the edge of the jellyfish body with other nerve cells.

The smallest kind of creeping jellyfish jellyfish in childbirth and Staurocladia Elevter, Bell drives from 0.5 mm to several millimeters in diameter, or with short tentacles to go beyond this, where these tiny jellyfish crawling on algae rocky ground pools. Hydro-jellyfish Cladonema radiatum and Cladonema californicum are also very small, living for a few months, but never growing a few mm in height and diameter of the bell is another small species of jellyfish is the Australian Irukandji, which is about the size of a fingernail. The lion's mane jellyfish, Cyanea capillata considered the largest jellyfish, and possibly the longest animal in the world, extending from the thin, threadlike tentacles that can be up to 36.5 meters (120 feet) long (though most of them are not so long great quotes) you have a moderately painful, but rarely fatal sting.

More huge Nomura jellyfish, Nemopilema nomurai in some, but hardly all years in the waters of Japan, Korea and China in summer and autumn is a much better candidate for "largest jellyfish", since the largest Nomura's jellyfish in late autumn can be 200 centimeters (79 inches) hood (body) in diameter and about 200 kg (440 lb) to achieve weight, on average, the sample is often as high as 90 centimeters (35 inches) in diameter bell, and about 150 kg (330 lbs) in weight. The large mass of the bell giant Nomura jellyfish can shadow diver and almost always much more than before, up to 100 centimeters (39 inches) Mane bell diameter Lion.

There is rarely a deep giant jellyfish Stygiomedusa another solid candidate for "largest jellyfish", with its thick, massive bell to 100 centimeters (39 inches) wide, and four thick, "belt, as" oral arms, legs and 6 (20 feet) in length, are very different from the typical fine, threadlike tentacles. umbrella of the more typical kind of jellyfish rim, including the lion's mane Most jellyfish and jellyfish polyps generations turn over their entire life cycle. Develops after fertilization, a primitive form of the free larva called planula. Planula covered with cilia, small larva. Some polyps can also produce asexual form of creeping frustule larvae, which then develops into a new polyp. Polyp usually planted stalk with a mouth surrounded by upward-facing tentacles.

Polyps may individually or colonial. Polyp colonies were formed by contraction, some polyps that have the general peritoneal cavity. Most polyps are very small, measured in millimeters. Polyp stage may last for years. Finally, the results of the polyp stage of a jellyfish. New jellyfish are usually created asexually by budding or budding from polyps. Medusa stage of life, which is most commonly defined as a jellyfish. Jellyfish reproduce both sexually and asexually. Spawn on reaching adult size, jellyfish in the day, when it is full. Jellyfish are usually either male or female (hermaphroditic individuals are rare.) A few jellyfish species can lead to new medusae by budding directly from the stage medusan. Promising sites, depending on the tentacle bulbs, the handle (above the mouth), or the gonads hydro jellyfish. Several types of jellyfish hydro fission (splitting in half) to breed.

Asexually in the second stage, the tiny polyps produce jellyfish, each of which is also known as a jellyfish. Tiny jellyfish (usually only one or two millimeters in diameter) swim away from the polyp and then grow and feed in the plankton jellyfish radially symmetric, umbrella shaped bodies are like a bell, which is usually supplied with marginal tentacles - fringe expansion Bell catch limit prey. A few species of jellyfish polyps are not part of the life cycle, but go from jellyfish to the next generation of jellyfish through direct development of fertilized eggs. Most jellyfish are., The second stage of its life cycle, larval planula stage, after the first phase of egg and sperm Although this long stage jellyfish, is an important stage, when the fertilized egg there that have undergone embryonic development, hatch and planulae from the females mouth or brood bag on their own and

Although most jellyfish marine animals inhabit some fresh water. It is most often used for hydro-jellyfish (actually many hydrozoans inhabit freshwater). The best known example is a cosmopolitan freshwater jellyfish, Craspedacusta sowerbii. Some of the other populations of jellyfish have been limited in the lakes, such as jellyfish lake in Palau. Creeping small jellyfish and Staurocladia Elevter (see size above) does not know how to swim, and "walk" around. Fronds on algae or rocky soils on jellyfish tentacles Most hydro and scyphomedusae, which is in the coastal habitat at the bottom on a regular basis, where they can stop swimming for a while, and certain types of box jellyfish on the seabed in shallow water. Even some of the deep-sea species of jellyfish and hydro scyphomedusae of most or collected at the bottom.

1961, Osamu Shimomura extracted green fluorescent protein (GFP), and another bioluminescent protein, called aequorin, from the large and wealthy hydromedusa Aequorea Victoria, the lead while studying photoproteins bioluminescence in this species. Martin Chalfie figured out how to use GFP as a fluorescent marker genes inserted into other cells or organisms. Artificial GFP show typically a fluorescent label, in which cells or tissues express specific genes. Disable the nematocysts (stinging cells) prevents further injection of venom. Salt water is an option, if no vinegar. Ice or fresh water should be applied to the sting, as this may help the nematocysts toxins remain free
