Part of the “Crabtree Connections” series, this title is categorized as an information book and it briefly introduces the creatures that live in the ocean. Young readers will learn that fish that travel in a group are called a school and that a coral reef is made up of animals not plants. Many fish live on the reef but only the clownfish is able to live among the toxic tentacles of a sea anemone. Fish use their fins to swim and the flying fish can actually glide in the air for 30 seconds. In the deep parts of the ocean fish have made special adaptations and one of the more unusual ones is the angler fish.
