Where Do Seals Live Mostly?

Six different species of seal live in Antarctic waters: Ross, Weddell, crabeater, leopard, fur and elephant seals. Fur seals are the smallest, with adult females weighing only 150 kg, while male elephant seals can weigh 4000 kg.

What do earless seal eat?

Seals are carnivores, eating mainly fish, though some also consume squid, other mollusks, and crustaceans. Unlike other seals, the leopard seal (Hydrurga leptonyx) of the Antarctic feeds largely on penguins, seabirds, and other seals, in addition to fish and krill.

Where do seals live land or water?

Seals are semi-aquatic, meaning they spend part of their lives on land and part in the water. Seals “haul out” on land to rest, thermoregulate, molt, and give birth.

Can seals live in freshwater?

Overwhelmingly, seals are marine mammals. Of the 33 existing species of pinnipeds—the taxonomic group that includes seals, sea lions, and walruses—only one lives exclusively in freshwater: the Baikal seal. At an average of 150 pounds and just over four feet long, Baikals are among the more petite seal species.

Where do seals live in the US?

They occur on the U.S. East and West coasts. On the East Coast, harbor seals are found from the Canadian Arctic to the Mid-Atlantic. Harbor seals are found all along the West Coast of North America, from Baja California, Mexico to the Bering Sea.

Where do pinnipeds breed?

Most males mate with multiple females, but some pinnipeds are monogamous. Mating and birth occur on coastal land or ice or on ice floes.

Where did Phocids evolve?

Other early fossil phocids date from the mid-Miocene, 15 million years ago in the north Atlantic. Until recently, many researchers believed that phocids evolved separately from otariids and odobenids; and that they evolved from otter-like animals, such as Potamotherium, which inhabited European freshwater lakes.

Who is the top predator in the Antarctic?

Leopard seals (named as such for their characteristic spotted coats), are one of the primary predators in Antarctica. In the wild they can survive up to 15 years, and are considered the most fearsome of all seal species.

Is walrus in Arctic or Antarctic?

Walruses live in Arctic and sub-Arctic regions of the world near the North Pole. They can be found in the Pacific Ocean, Atlantic Ocean, and Arctic Ocean.

Why do seals have weird teeth?

The unique shape of their teeth allows leopard seals to feed efficiently at both the top and bottom of the Antarctic food web, increasing their feeding options and therefore, their chances of survival.

Do seals live in the Arctic and Antarctic?

Many different species of seal live in both Antarctica and the Arctic, and life cycles vary considerably among species. Some species depend entirely on the presence of sea ice to survive.

Do seals live in the polar region?

The Arctic is home to several unique—and uniquely beautiful—seal species: ribbon seals, bearded seals, ringed seals, spotted seals, harp seals, and hooded seals. These Arctic species are called ice seals because they spend the bulk of their lives on or near sea ice.

Where do seals sleep at night?

Seals sleep in the water as well as on land. In the water, they sleep floating in a standing position, like a fishing bobber, or floating horizontally on the surface. Because they are sleeping and not actively swimming, they can stay under water much longer than when hunting for food.

Where do seals go in the winter?

Seals prefer rocky, secluded islands and beaches, but will often haul themselves up on piers in harbors and coves such as Apponagansett Bay, New Bedford Harbor, and Nasketucket Bay.

How many phocidae are there?

Phocidaeseals. This diverse group contains 19 species in 10 genera. Phocids are broadly distributed along coastlines above 30 degrees N latitude and south of 50 degree S latitude.

Why seals have no ears?

Underwater Aural Skills

The harp seal’s absence of pinnae is not without a purpose. The absence actually contributes to the seals’ abilities to pick up on direction in hearing, which they utilize to their advantage both underwater and above the surface.

What are the 3 families of pinnipeds?

Pinnipeds are separated into three groups: earless seals, eared seals and walruses. Sometimes referred to as earless seals or true seals, marine mammals in the phocid family can be easily identified by looking at their ears and flippers.

How do Phocids move on land?

Although graceful swimmers, phocids are not agile on land and typically “phocidulate”; that is, they move by undulating or heaving the body in a caterpillar-like manner.

How long can a pinnipeds stay underwater?

Seals dive for three minutes at a time typically, but they can stay under water as long as 30 minutes and dive as deep as 1,600 feet.

Where do GREY seals go in winter?

During the winter months grey seals can be seen hauled out on rocks, islands, and shoals not far from shore, occasionally coming ashore to rest.

How long can seals live out of water?

How long can seals stay out of the water? Seals can stay out of the water for extended periods of time, depending on the needs of the individual animal. It can be completely normal for some species of seals to spend several days to even a week at a time out of the water.

Do seals mate in the water?

Copulation usually takes place in the water. A male harbor seal may mate with several females.
