The photography helps young viewers see the close-up details of each animal. Footless snakes and worms crawl, sea anemones take root, and starfish swim. Animals that hunt or are hunted need excellent hearing. Rabbits and elephants lose body heat through their ears. The ears of owls, ostriches, and grasshoppers are hidden.
Bats use their ears for echolocation.
Tails help animals balance and are handles for elephant babies, bushy blankets for snow leopards, and chairs for wallaroos. Even brightly colored animals are hard to see in certain environments. Others look like their surroundings. Armor, bad smells, and bad tastes protect goliath beetles, skunks, and butterflies. Insect eaters prey as efficiently as leopards and sharks.
