"The World of Reptiles and Amphibians" by John Honders (editor)

1975, oversize American hardcover edition, Peebles Press, NY. 160 pages. Tons of information throughout. Remarkable 112 pages in full color. Authoritative text.

Note: The publishers recommend this title for adults. There are photos of snakes, crocodiles, and alligators capturing prey that may be too much for youngsters. (Unless, of course, your youngster has a firm grasp of how the natural world works and would not be shocked at such images.)
