Sea Otter. The sea otter is the largest member of the weasel family and the smallest marine mammal. Ninety percent of the worldâs sea otters live in coastal Alaska. The Marine Mammal Protection Act protects sea otters. It prohibits commercial harvest of sea otters, and allows Alaska natives to hunt sea otters for subsistence and creation of handicrafts. Sea otters were hunted nearly to extinction in the late 1700s and 1800s through commercial harvest for their luxurious furs. Once commercial harvest ceased, sea otter numbers rebounded and they re-colonized much of their former range. Sea otter numbers have declined in southwestern Alaska over the past 20 years.
They can store extra food, and rocks used as tools, in these pockets. Sea otters have a high metabolic rate (that is, they use a high amount of energy) that is 2-3 times that of other mammals their size. Sea otters eat about 20-30% of their body weight each day. Otters weigh from 35-90 pounds (males weigh more than females). So, a 50-pound otter would need to eat about 10-15 pounds of food per day. The food sea otters eat can impact the entire ecosystem in which they live. Sea otters have been found to play a pivotal role in the habitat and marine life that inhabit a kelp forest.
