What Do You Use From A Seal Animals

Common Name :: Seals
Scientific Proper noun :: Pinnipedia
Diet :: Carnivore
Boilerplate Life Span In The Wild :: Upwardly to 30 years
Size :: 3 feet to twenty feet long
Weight :: 100 pounds to 4.4 tons

In that location are 33 species of pinnipeds alive today, most of which are known as seals. Pinnipedia is made up of three master groups: The walrus, which is the simply living member of the family Odobenidae; the eared seals of Otariidae, including numerous kinds of fur seal and sea lion; and the earless seals, known as true seals or Phocidae. Despite the proper name, earless seals have ears—they're merely hidden beneath the surface of their skin.

Pinnipeds can be found on every continent on Globe, though most species occur in cold-water environments. Thick layers of fatty, also known as blubber, keep the animals warm, in addition to dense fur. Walruses are the exception to the rule, every bit these big, tusked pinnipeds have most hairless bodies.

Seals range greatly in size, from the gargantuan southern elephant seal, which can weigh more than than a pickup truck, to the relatively slender, 100-pound Baikal seal.

While there are many differences amongst the species, all seals have feet shaped like fins. In fact, the discussion pinniped means "fin-footed" in Latin. Those fin-shaped anxiety brand them supreme swimmers, and all pinnipeds are considered semi-aquatic marine mammals. This means they must spend some part of their lives on land or sea ice, ordinarily during the mating and birthing seasons.

With so much fourth dimension spent in water, some species similar the elephant seals accept evolved the ability to hold their breath for upwards to two hours and dive to depths of more than half-dozen,500 feet looking for food. (Read more well-nigh how diving animals tin stay underwater for then long.)

Nearly all seal species are reliant on marine habitats, though some will enter estuaries and rivers in search of nutrient. An outlier is the Baikal seal, which spends its whole life in Lake Baikal, a freshwater lake in Siberia.

Evolutionarily speaking, seals are idea to be most closely related to bears and the grouping of animals that includes weasels and otters, likewise as skunks, raccoons, and ruby pandas.

Varied diets

All seals eat other animals, and nearly rely on fish caught out at sea. Merely a few species break the mold.

For instance, leopard seals make a living hunting down penguins and fifty-fifty other seals. And walruses survive on a diet of clams and other shellfish, which they detect with their highly sensitive whiskers and then suction up from the seafloor with their powerful mouths.

There is too a species of pinniped known as the crabeater seal, which lives in Antarctica. Nonetheless, these animals don't eat venereal at all—at least not the kind you would think. Instead, these seals apply highly specialized teeth to filter h2o for tiny, abundant crustaceans known equally Antarctic krill.

Pinnipeds in peril

Historically, hunters take heavily targeted pinniped species for their fur, a practice that drove some species to extinction: The Caribbean monk seal, for instance, disappeared from the planet in the 1970s. Though hunting is more regulated today, the animals still face many threats, including lack of nutrient, entanglement in angling gear, and conflict with fishermen. Some species, like the Hawaiian monk seal and Mediterranean monk seal, remain very shut to extinction.

However, climate change represents the unmarried largest threat to many species of pinnipeds, especially those that rely on sea ice. Various species of Arctic seals rely on ice for breeding, for instance, while walruses utilize seasonal ice formations to forage for food further from shore. (Read how climatic change is changing what leopard seals eat.)

Ringed seals build caves in the snow and create holes in the ice that give them access to the ocean. If that snow melts earlier than usual, information technology will put the animals at greater risk of predation from polar bears.
