Otters

Yes, they eat other living things. Like oysters, mussels, crabs. But they can also be called omnivores.'Cause they eat plants and such too.

Sea Otters sleep in groups while wrapped in seaweed so they do not float away. The Alaskan Sea Otter will occasionally haul out on ice or rocks and sleep. It is very uncommon for California Sea Otters to haul out.

Sea otters were not invented.

Predators of river otters include bears, eagles, wolves, coyotes, foxes and cougars .

yes otters have flaps of skin, much like that of a kangaroo on each side of their waste. these "pockets" are very wet and the saying 'wetter than an otters pocket' comes from this fact. these pockets are generally used for holding useful items like keys and lipstick.

The Sea otter or Kalan (Enhydra lutris) is a large otter native to the North Pacific, from northern Japan and Kamchatka east across the Aleutian Islands south to California.

The sea otter is capable of living exclusively in the ocean. The sea otter inhabits near shore environments where it can quickly dive to the sea floor to forage. Sometimes they rest in coastal kelp forests, often draping the kelp over their bodies to keep from drifting away. Most otter species have at least one permanent burrow or den by water. The burrow's main entrance may be under water. River otters dig their own burrows. They are found most often in areas with protection from the most severe ocean winds, such as rocky coastlines, thick kelp forests, and barrier reefs. Sea otters can also live in areas where the sea floor consists primarily of mud, sand, or silt.

yes of cause they do :)

No known species of otter is presently extinct, although several in the past were believed to be extinct. These include the sea otter, as well as most recently, the Hairy-nosed otter, which was rediscovered in Southeast Asia in 2005.

There are several bird species that are found in River Thames, including The Mute Swan, The Canada Goose, The Mallard Duck, The Greylag Goose, The Great Crested Grebe, The Coot, The Grey Heron and The Moorhen. You can also find mammals such as The Water Vole, The Otter and The American Mink.

otters spray and bite

by far polar bear because the live in much colder weather then sea otter

No they do not. That's why they come up every once in a while.

Mammals are animals that MUST breathe air to survive. All otters areammals

There are many types of river otters, and some are social while others are not. The Giant River Otter from the Amazon lives in packs, as do North American river otters, female Southern river otters, (males are solitary). The European river otter is extremely territorial.

If a sea otter get hold of something with a hard shell it will float on its back with the 'hard-shelled thing' on its belly and smash at it with a rock it has also procured. They're quite cute to watch doing this. After the thing has been smashed open then they eat it with their mouths as you would expect.

It differs by where the otters are. But the predators are great white sharks, killer whales, and sea lions.

It varies on the size of the pod. There can be hundreds to thousands in a large raft. Often females and males stay in separate groups, although the alpha male is not far from the females and pups.

How big an otters tail really depends on which species you are referring to. Through the different species, the tails can range anywhere from 30 to 51 cm.

It does not really matter what source of water they are living in. As long as the water has a steady food supply and good conditions for them they will live there. Otters have been known to live in cold climates and warm. So food and the cleanliness of the water is really what counts for them.

River otters have much longer tails and a longer head than the sea otter. Sea otters have have large webbed hind flippers. When at the surface, river otters tend to swim on their bellies. Sea otters float on their back. River otters would be more likely to climb on a log or onshore to eat. Sea otters tend to eat their food in the water while floating on their backs, with the food on their stomach. River otters are on land frequently. Sea otters almost never leave the water. River otters tend to be all brown. Adult sea otters' heads lighten throughout their lifetime, becoming quite blond.

In addition to the above, Sea Otters often gather in large numbers called "rafts" while river otters are more solitary and are usually only seen in groups of 4 or less (mom and pups). River otters can be found in streams, rivers and coastal salt water areas.

They are a vital part of the ocean's ecosystem. Without otters, sea urchins would have no predators and would overpopulate and likely destroy kelp forests, which are a food source for urchins.
