Books in Animal Scientists series

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.

Animals build an incredible array of structures in which to sleep, raise young, or catch prey. Some structures involve excavating in subsoil or wood, others involve construction underwater, and some are fixed to trees. Polar bears dig out caves in the snow to protect themselves from the coldest weather. Spiders spin webs of incredibly strong silk to ensnare prey. Prairie dogs dig underground 'towns' that can house hundreds of families.

FOR USE IN SCHOOLS AND LIBRARIES ONLY. Lions and scorpions and lethal little jellyfish, oh my! Kids will sink their teeth into this fascinating look at nature's fiercest creatures. Sometimes nature can be nasty: snakes that spit poison, insects with exploding bottoms, and tigers that have you for dinner. Throughout the animal kingdom, creatures are equipped with lethal weapons, from finger-length fangs to toxic tentacles, and have ingenious ways of killing one another - poisoning, dive-bombing, strangling, and even electrocuting! Discover the murderous methods of attack and defense that make animals armed, dangerous, and deadly.
