Sea Snakes

Pp. vi, 148; 29 color photos, numerous text-figures (line-drawings) and some black-and-white photos.  Color pictorial stiff wrappers, sm 4to.  The sea is a habitat alien to most reptiles, and the adaptation of sea snakes to a marine existence is a fascinating chapter in biology. Sea Snakes describes the varieties and distributions of sea snakes, how they go about their daily lives underwater, what they eat and what eats them and how they reproduce and grow.  It also discusses how sea snakes cope with excess salt and scarcity of fresh water, and how they adjust to diving at depth and enduring long periods without breathing.  The nature of their venom and how it functions in subduing large, active prey is also explained.  Sea snakes also interact with humans both in beneficial and in harmful ways.  The author explains these and discusses how we can best share the world with these beautiful and marvelous creatures (from the rear wrapper blurb).  No ownership marks.
