Sea otters live in shallow coastal waters in the northern Pacific Ocean. Two sea otter subspecies occur in the United States, the southern sea otter (Enhydra lutris nereis) and the northern sea otter (E.l. kenyoni). Southern sea otters, also known as California sea otters, live in the waters along the central California coastline.

While northern sea otters did not receive a similar listing, oil spills are also a significant threat to these animals; the Exxon Valdez oil spill in 1989 demonstrated the severe and long-lasting impacts of oil spills on this species. Southcentral Alaskan sea otters near Prince William Sound were severely impacted by the Exxon Valdez oil spill.

Northern sea otters (E. lutris kenyoni) from Alaska and southern sea otters (E. l. nereis) from central California have since recolonized or been reintroduced in parts of their historical range. In the late 1960s/early 1970s, northern sea otters were used for reintroductions in southeast Alaska and the outer

Sea otters are well?known to prey on sea urchins that would otherwise over?graze kelp. Sea otters have also been documented to prey on large crabs in the Elkhorn Slough (CA), which would otherwise limit the abundance of mesograzers (isopods and sea hares) that fed on epiphytic algae growing on seagrasses. The presence of sea otters in ...

Sea Otters. Sea otters, beloved for their fuzzy and charismatic appearance, also make substantive contributions to coastal health. Perhaps the most well-known example is sea otter consumption of urchins, which in turn reduces urchin predation on kelp, allowing kelp forest habitats to thrive, reducing shoreline erosion and promoting biodiversity.
