This may also happen in other areas.

Bringing back sea otters to the Oregon Coast just got a high-level endorsement. However, many new populations in formerly vacant habitats have increased steadily at rates as high as 17 to 20 percent per year, indicating that in areas where populations have not reached the limits of their habitat, natural mortality levels must also be quite low.

When lying face-up they move slowly by sculling the tail or paddling with one or both hindlimbs. With their elevated metabolic rates, sea otters must consume large quantities of these invertebrates and thus they have high exposure rates to the associated parasites and pollutants. Following reintroduction, the Sea Otter population in Canada has increased to about 900 animals and has been growing at a rate of 17 to 20 percent per year. Hundreds of thousands were also obtained along the Alaska to California coastline. Finally the fur is aerated by blowing into it or churning the water to a froth with the paws. Expansion to new areas will also provide increased opportunities for the public to view this engaging animal in the wild.
