Book Description: A beaver slaps its tail on the water to warn other beavers of approaching danger. A mother bat returning to the cave can locate her baby among two or three million other bats by using a special cry. And the male hippopotamus marks his territory by spinning his tail and scattering his dung. These are just a few of the unusual ways animals communicate with one another. This beautifully illustrated work by noted author and illustrator Steve Jenkins describes many more fascinating and curious ways of animal communication.
