内容简介 How do frogs swallow with their eyes? Easily. When swallowing a big mouthful of food, a frog blinks its eyes. The blinking pushes the frogs huge eyeballs down on top of its mouth. This helps squeeze the food in its mouth into its throat. WHOOSH!-down goes its meal!In this superb introduction to amphibians, children will uncover many facts about these cold-blooded creatures. The Bergers discuss key curricular topics, like metamorphisis and molting, in an accessible manner and the vivid illustrations of Karen Carr make these animals jump right off of the page!
