Debunking some common myths and commenting briefly on such separate topics as snakes' senses, habitat, locomotion, and defense, Leen's slight but serviceable text is accompanied by close-up black-and-white photos and photo-sequences which, though occasionally unclear, will be the main attraction here. Before our eyes a king snake crosses a horizontal vine in his own high-wire act, a corn snake emerges from its egg, a Western shovel-nose disappears into the sand, a rat snake sheds its skin, a cobra spits poison across the page, while other sequences show a California king snake killing and swallowing a rattler and an African egg eater engulfing an egg twice its thickness. Snake exhibits always draw crowds, and here are some performances you're unlikely to catch at the zoo.
