This colophon was written by Nancy Kotary. Species vary in size and appearance, with the largest having a leg span of about nine inches. Most species eat large insects such as beetles, but some prey on small reptiles. The tarantula can also survive for very long periods without food or water. Another defense is to use one of their four sets of legs to fling hairs from the abdomen at perceived threats.
Tarantulas often appear sluggish, but can move quickly when necessary.
The molting process frequently restores lost limbs. Various tarantula species are kept by many people as pets. The name is thought to have come from the Italian town Taranto.
