Branch Head pinnipedia walrus fins odobenidae Section walrus walrus containing only one kind of life in the Arctic Sea. Walrus most striking is the one on the huge tusks, female and male are great, this is it and other Pinnipeds different places, which is actually from the maxillary teeth grow canines, such as ivory , his life grows constantly. When foods such as digging, climbing ye stone or attack the enemy, this stuff is an indispensable tool or weapon. Walrus forefoot very long, about a quarter of the body length, hind legs can bend forward, so to walk on land. Ears only slightly thicker skin, cartilage does not support (with seals similar). Huge body (after the trunk seals), all day long on the ice or shore up late, it seems very heavy, but can be very agile in the water activities. Its delivery is carried out in the sea. In order to access their human teeth, grease and meat, in a lot of killing, the existing number has been very less. Walrus is a rare animal, but also an economic Marine Mammals. As the number of countries competing for hunting, the number of walruses are dropped from millions head two or three centuries ago to today, about 70,000 less. Walrus on land and as little resemblance in appearance. Walrus body huge and ugly shape, rough skin and more wrinkles, fine squint eyes, fangs protruding outside. Walrus is swimmer's performance in the water much more sensitive than on land. In order to adapt to marine life, walruses can also change the body color. Because there is a strong gregarious habits of walrus, if similar injuries, they are bound to go for help, and never abandoned due to disregard their own safety, which makes it easy to capture human; international marine mammal protection regulations enacted in 1972 has put Walrus as protected objects, the prohibition of arbitrary killing. In the high-latitude oceans, in addition to large whales, walruses can be described as the largest mammal, and have claimed that it is the residents of "indigenous" in the northern hemisphere. Nineteenth century, because of the wanton killing of walrus that it was drowned, animal scholars also had solemnly declared: walrus on Earth has disappeared. Perhaps because of the large hunting disaster survivors escaped with five double the fecundity, walrus and prospered over the past century. As the sea 100 km from San Francisco has only three square kilometers on a small island, with 130,000 living on walrus. Walrus that huge body, quirky looks and strange habits, not only to make people surprised, but also to scientists puzzled. It is round, short and wide mouth, thick nose, upper canine teeth forming up to 40 cm -90 cm fangs, each 4 kg or more. Male walrus body length of up to 5 meters and weighs four tons. Walrus hind legs can bend forward, posted on the belly, in the land that it can move forward. Walrus likes gregarious, surrounded by thousands of heads together. Summer As a result, they will travel in droves to the mainland and the island shore, or climb up the sun on a large piece of the iceberg. Visual difference walrus, his eyes squint old man like lack of energy. They love to sleep late in life most of the time is spent lying on the ice, but also to sleep in the water. When flat sleeping, half a back seat floating above the water like a small hill, with wave fluctuations. Straight to sleep, head and shoulders exposed, breathing very convenient. Walrus why can sleep it straight? Turns out it's throat with a balloon, when filled with air, making it like a balloon suspended in the water. Walrus very sensitive sense of smell and hearing, when they sleep, there is a walrus patrolling around, in case the situation on the issue of the bull-like sounds, the sleeping walrus wake, quickly fled. Walrus bulky body, but action is very agile, able to swim across the choppy rock phosphate Xun, but also hundreds of kilometers across the Strait! Walrus subcutaneous fat layer about three inches thick, can be cold insulation. Walrus on land and sea in the color of the skin is not the same as in the vascular heat onshore expansion, brownish red. In the water, the blood vessels shrink, the blood from the subcutaneous fat layer extrusion to enhance the seawater heat capacity, which is white. For a long time, people know very little about the habits of walrus, especially the role that large fangs, so scientists puzzled: If you say it is a weapon of self-defense, but in the high latitudes, there is no rival walrus, polar bear turn away from it. Ferocious orcas may chase it, however, walrus always "go for the best," and that it never will advance scientific fangs and orcas. So to increase the load walrus tusk Could the head, making it easy to go deep water diving? If so, this assumption is not to increase the difficulty of walrus floating it? With walrus tusks sometimes climbing iceberg, or use it to duel with the rival, but this does not explain the main purpose fangs. In order to clarify all of this mystery, foreign scientists to the walrus's hometown - Hudson Bay to inspect. It turned out that as the plow-like fangs in the seabed with hard work, plow showing two trails about 50 cm deep furrows. When plowed 2 m -3 m, walruses on the forelimb stretch upstream, before its two pinniped tightly closed, holding a harvest tour side edge rubbing, dragging behind one black "smoke." When a fast swim to the surface, it is the prey cast, and turn back at different speeds according to sink, capturing meat such as conch, shellfish, mollusks. This is how extremely intelligent ah! There walrus mustache that dense and hard, but also help it in (such as "polar night" season) in poor light conditions accurately catch food. Of course, not all of the walrus are eating mollusks, crustaceans or other animals for a living. One particularly ferocious temperament walrus, designed to eat seals, sea hare's body, or even chase boat wounding. This walrus tusk yellow (usually white) Eskimos fear it crashed through the ship, causing the disaster. Every spring, walruses began the great migration. Chanzai female walrus, then enter the mating season. Newborn baby elephant seal weighing up to 40 kg, after a month of lactation may soared to nearly its weight kg. To two years old, it's up to 2.5 meters in length and weighing up to 500 kilograms, began living independently. Male walruses are indifferent to small walrus. During the mating season, they simply jealousy, competition for lovers killing each other, and some were killed, most of leaving scars. However, it is commendable that, once separated and the mother walrus, former rival of hatred all been forgotten, they soon formed a separate, friendly male groups. Female elephant seals, although not as walrus, depending on the child, such as life, but it is still a competent "Mom." Mother had each other, playing with each other. "Mom," before holding with fins "children", sometimes let dear baby riding in the back, hug the neck or sleeping in the "mother" body. If the small walrus injured died, "mother" will do everything possible to get it to the water burial. Once, an Eskimo killed in a baby walrus on ice along when he took the prey go, do not prevent sudden sprang mother walrus was behind the attacks; When he turned to find out how the matter when mother walrus carcasses have been with small walrus dive. If the mother walrus was captured, shouting will find a small walrus mother, with not bear to leave the ship after the hunt. Walrus there are other habits, such as on land, it is the implementation of "fasting", and do not eat anything, showing its unique metabolism. There are significant differences between male and female walrus weight, a 2.5 m-long female walrus, weighing about 700 kilograms, equal to half the weight of the same male walrus that other animals do not have. Walruses are accustomed to return "home" breeding births per one earners. Them year after year, never lost.

They grow fat, fat, limb like fins, which is both a tool walrus swimming in the water, it is also on the ice, "walk", "foot." Real name walrus is the hippocampus, but because it is long with two sharp tusks, ivory shaped like elephants, people vividly call it a walrus. Walrus tusks have many uses, it can be hard to peck open the shells, a walrus can eat hundreds of seashells it! Walrus tusks or its halberd and defensive weapons in the face so scary sharp teeth, who are not afraid! Although walrus in the water quite flexible, but the ice becomes very bulky. Curiously, dragging so bloated body, how it was from the sea "climb" shore it? Every walrus climb from the sea ice, it must rely on sharp tusks to help. I saw it severely headlong into the ice wall tusks, and then as the front foot fins help, through the smooth skin, a hard struggle, on the "Chi Liu," a decline on the ice. Walrus tusk is it really just another "foot"! Walrus tusks
