The Exxon Valdez oil spill in Prince William Sound, Alaska, in 1989 wiped out nearly half of the Sea Otters in the oiled area of the Sound; the much smaller Nestucca spill off Washington in 1988 killed at least one otter at Checleset Bay, 440 kilometres north of the spill site. Swimmers may stay underwater for a maximum of 15 meters at the start of the race and after turns. Reduced lobulation of the lungs is presumed to be adaptive for underwater swimming.

One study saw a male sea otter hold a struggling female underwater until she died during intercourse and ten months later, the same otter was seen swimming, diving, and having sex with a different female carcass. However, a 150-year period of ruthless exploitation began with Vitus Bering's exploration of the Aleutians and Gulf of Alaska in 1741.

River Otters seldom occur in groups larger than a single family (although families can include three or four young), don't rest on their backs, and come ashore frequently. The near extinction and subsequent increase of Sea Otters has allowed researchers to study their effects on benthic (seabottom) plant and animal communities as they recolonized or were transplanted into vacant habitats. This is made possible by a prodigious food intake (25 to 30 percent of body weight each day), an intestine 10 times the body length, and a rapid digestive rate. My grandson took lessons at Sea Otter.
