Why Are Pacific Walruses Endangered?

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 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?

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.

Why are Amazonian manatees endangered?

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.
