 The
sea otter is a lovely marine mammal. It is the
largest member of the weasel family. Sea otters
have thick fur to help keep them warm.
In fact, they have the thickest
fur in the animal kingdom. Other marine mammals
have a layer of fat to help keep
them warm. But unlike them, sea otters don't
have it.
The sea otter is one of the smallest marine mammals. Male sea otters
weigh 22 to 45 kilograms.
And they are 1.2 to 1.5 meters long. Females are smaller, weighing
14 to 33 kilograms. They are 1 to 1.4 meters long. Males can live
up to 10~15 years; females can live up to 15~20 years.
Sea otters live in shallow coastal waters. They spend much of their lives
in the water. They eat about 25 percent of their weight in food each
day. They usually eat mussels, clams, crabs, and about 40 other
marine animals.
Sea otters used to live all over the world. But people killed so many
of them for their fur. Today, only about 1,000~2,000 sea otters are
living in the wild. They can be found in California, Washington,
Alaska, Canada, Russia, and Japan. |
