Sea Otters

1.   Otters will wrap themselves with kelp to keep from floating away on the waves when they are sleeping.

2.   The sea otter has the thickest fur in the animal kingdom.

3.   The sea otter is the largest member of the weasel family.

4.   Females average 45 pounds, while males average 65 pounds. Northern sea otters can reach up to 100 pounds.

5.   Otters eat all kinds of slimy marine life such as clams, worms, fish, mollusks, octopus, mussels, sea urchins, crabs, and even snails. Each individual otter develops 2-3 preferences. For example one otter may like crabs and mollusks while another may like abalone and snails. Otters develop preferences to prevent competition for food between other otters.

6.   Sea otters can dive up to 180 feet in search of food.  An otter uses its nose and whiskers to help him in finding food and to detect vibrations under the water. They also use a pouch or flap of skin located under their forearm to store food until they get back home.

7.   Otters are one of the few animals who use tools to open up their food, sometimes an otter will lie on its back, take a rock and crack open a clam - some otters even stick their favorite tool in their armpit to save it for further use. 

8.   To maintain a normal body temperature, adult otters have to eat about 25% of their body weight per day. For an average adult male that would be about 50 sea urchins a day! For a 150-pound person, this would be the same as eating 160-quarter pound hamburgers.

9.    Male sea otters live an average of ten to 15 years, while female sea otters live an average of 15 to 20 years.

10.  Otters spend eight hours a day grooming, they must do this to stay alive, while grooming they rub and blow air into their fur creating air pockets, this provides insulation, which keeps them warm in the cold water.  Without blubber, their fur is essential for survival.
