Books with author Leon Gray

Sound, sight, and chemicals are all important as animals attempt to communicate warnings, information about food, to attract a mate, or sometimes just for pleasure. Whales communicate across hundreds of miles of ocean with ultrasound 'songs.' Fireflies uses flashes of light to attract a mate. Skunks squirt foul-smelling chemicals to ward off attackers.

Finding prey and detecting predators are life-or-death matters for animals. They use some technologically advanced systems including the senses we're familiar with-and others that are far more sensitive. The book explains how bats use echolocation to hunt on the wing, tells how sharks can smell tiny amounts of blood from hundreds of yards away, and how supersensitive hairs on a spider's body can pick up vibrations in the air.
