The Pacific walrus, which inhabits the Arctic seas between Alaska and Siberia, is at increasing threat of extinction due in part to global warming.
Inland population shifts such as this have led to overcrowding and deadly stampedes.
Is a walrus an endangered species?
Data deficient (Data inadequate to determine a threat category)
Why is the walrus population declining?
An increase in hunting during the 1980s served to exacerbate the decline, she says. She says changes in sea ice conditions could also affect Pacific walrus populations. It is difficult to estimate populations of walrus, because the animals spend a good bit of their time foraging underwater.
How many walruses are left in the wild?
The worldwide walrus population is about 250,000 animals. Pacific walruses number more than 200,000.
Are Atlantic walruses endangered?
The Atlantic Walrus has suffered from many years of hunting and its Northwest Atlantic population is now listed as extirpated (extinct in Canada) and protected under the federal Species at Risk Act ( SARA ).
Why are manatees endangered?
Manatees are slow moving and gentle aquatic mammals under threat. They were recently on the endangered species list and are still threatened because of the following: Habitat loss, including destruction of or blockage of natural warm spring water they need to survive in the winder.
How big is a walrus Weiner?
The walrus has a particularly impressive baculum, up to 22 inches in length. The bone was even larger in the past. A fossilized, 4.5-foot os penis of an extinct walrus species fetched $8,000 at auction in 2007. But humans, curiously, do not have penis bones.
Do walruses eat humans?
Because of their size and tusks, walruses only have two natural predators – killer whales and polar bears. However both predators prefer to attack easier prey like seals. Humanity is historically the greatest hunter of the walrus.
What can eat a walrus?
The walrus is a large animal that has only two predators: the polar bear and the orca, or killer whale. Orcas attack walruses that are in the water, and polar bears attack them on land or on ice floes. Polar bears usually avoid tackling adult walruses because they fear being injured by their long tusks.
What is the lifespan of a walrus?
LIFE CYCLE: The maximum lifespan of a walrus is approximately 40 years. FEEDING: Walruses eat clams, crabs, shrimp, soft corals, sea cucumbers, and various other mollusks. They use their extremely sensitive “whiskers” to identify food.
Can a polar bear kill a walrus?
In the water, walruses are out of reach for polar bears. In fact, an aggressive walrus can be dangerous for a polar bear in the water. In the water, too, walruses generally react to polar bears as to predators – they fear and avoid them. Only rarely do they attack.
What do you call a group of walruses?
A Huddle of Walruses
A group of walruses can also be called a ‘herd’ or a ‘pod’, but we like ‘huddle’ best.

Where are walruses found?
Atlantic walruses inhabit coastal areas from northeastern Canada to Greenland, while Pacific walruses inhabit the northern seas off Russia and Alaska, migrating seasonally from their southern range in the Bering Sea—where they are found on the pack ice in winter—to the Chukchi Sea.
What species are endangered?
Top 10 Most Endangered Animals
- Amur Leopard. Since 1996, the amur leopard has been classified by the IUCN as Critically Endangered with less than 70 individuals thought to exist today.
- Sea turtles.
- Sumatran Elephant.
What do Atlantic walruses eat?
Food Preferences & Resources
Walruses prefer molluscs – mainly bivalves such as clams. They also eat many other kinds of benthic invertebrates including worms, gastropods, cephalopods, crustaceans, sea cucumbers, and other soft-bodied animals. Walruses may occasionally prey on fishes such as polar cod.
Why are Amazonian manatees endangered?
The Amazonian Manatee is considered endangered by the IUCN. The Amazonian manatee has been heavily hunted by subsistence and commercial hunters. It has been sought for meat, oil and fat, and at one time for its hide, which was in demand for use as water hoses and machine belts.
Why are sea cows endangered?
So what has caused manatees to become endangered? There are two major threats: loss of habitat and collisions with boats and ships. As new developments are built along waterways, natural nesting areas are destroyed. Sewage, manure, and fertilizer run-off enters the water and causes algal blooms.
Why are sea turtles endangered?
Nearly all species of sea turtle are classified as Endangered. Slaughtered for their eggs, meat, skin and shells, sea turtles suffer from poaching and over-exploitation. They also face habitat destruction and accidental capture in fishing gear. Climate change has an impact on turtle nesting sites.
