HANGING ON

A collection of animal profiles, for junior behaviorists who'd like to see a beaver carrying its kitten like a stack of wood, or a sea otter roping itself to a pup with seaweed. Subjects, ranging from the familiar kitten-toting cat to the piggybacking pangolin, are illustrated by assorted sequential and close-up black and white photos. Though specific differences in parental dependence are mentioned, the general procedural approach adds little to the many animal baby books available.
