Animals with No Eyes: Cave Adaptation (Extreme Life)

Description

Describes adaptations that occur in a cave environment, including general adaptations and examples.

A cave has three different zones: the entrance zone, the twilight zone, and the dark zone. The creatures that live in the dark zone are creatures that never see the light of day--and have adapted very well to their environment. This book, one in the "Fact Finders: Extreme Life" series, teaches about these dark zone cave dwellers. Because light does not enter their environment ever, most of these troglobites do not have any eyes or any color to their bodies. They are so adapted to their environment that they could not live anywhere other than the dark zone of a cave. The blind cave tetra, glowworms, no-eyed big-eyed spider, cave crayfish, cave millipedes, cave fish and grotto salamanders are just some of these extreme animals. The book not only discusses such amazing creatures, but each page is full of large color photographs. These brilliant illustrations help readers to feel as if they were in a cave, looking at these troglobites themselves.-- "Children's Literature Comprehensive Database"
