FORM AND FUNCTION In this section I will briefly describe some of the sea otter’s basic biology and discuss how several aspects of the species’ form and function are integral to what I see as the three main dimensions of their conservation and management—exploitation and recovery, fishery conflicts, and marine pollution. Insulation Homeothermy at or around 37 C is a feature of all birds and mammals, demanding in turn a careful balance between heat production and heat loss. In contrast with pinnipeds and cetaceans, which use blubber for insulation against heat loss to the cold aquatic medium in which they live, sea otters depend entirely on their fur.

Prey type and size depends on location, habitat type, season, and length of occupation (see Chapters 6 and 10 for further analyses of sea otter diets). , 1981). In protected bays with mixed sediments, otters mainly consume infaunal clams (Saxidomus nuttallii and Tresus nuttallii; Kvitek and Oliver, 1988). Along exposed coasts of mixed sediments, the Pismo clam (Tivela stultorum) is a common prey (Stevenson, 1977). , 1989). The predominately mixed-sediment habitats of southeast Alaska, Prince William Sound, and Kodiak Island support populations of clams that are the primary prey of sea otters.
