I am a sea otter. My scientific name is enhydra iutris. A couple of fun facts are there are only 13 types of different sea otters in the world. A group of sea otters are called a raft. Newborn pups cannot sink or dive. Sea otters are a part of a the weasel family. Sea otters can remain in water over 4 minutes. The Sea Otter population is 100,000 to 150,000. We can save sea otters by staying green.
