Burning questions of the animal world are answered here: Does a bird have a big black wet nose? Does a fish have a long tongue? With a loud ``No'' to every question but one, Walsh's debut acts less as a primer in zoology than as a template of the question-and-answer format. It may be a toddler's first quiz book. Simple, Lucy Cousins-like illustrations reinforce the regularly paced queries, with rough forms against bright backgrounds. The work is easily mastered, and doesn't bear rereading, but certainly has its charms. (Picture book. 3-5)
