Seven unusual animal fathers are presented in text and color photos: sea horse, three-spined stickleback fish, giant water bug, hip-pocket frog, Chilean flamingo, red fox, and cotton-top tamarin monkey. For each, the authors describe how specialized anatomy and behavior patterns of the male parent help the young animals survive. The slow-moving sea horse papa has a special pouch where he keeps the eggs till hatching. The male stickleback fish prepares a nest and guards both eggs and young fry. The male hip-pocket frog has special pouches to keep tadpoles safe until they become frogs. And father cotton-top tamarins, tree-dwelling monkeys who usually have twins, help out by carrying the young. Scientific names are not given. Additional information on size and range would have been helpful. The authors of many popular animal titles, including Scaly Babies: Reptiles Growing Up (1988) and Slippery Babies: Young Frogs, Toads, and Salamanders (1991), have written another book that will be popular with animal enthusiasts.
