Like other spiders, tarantulas do produce silk for webs of all sorts. Some make webs that look like tubes while others use their silk to strengthen the walls of their underground burrows.
Habitat: Tarantulas can be found throughout the world—United States, Central and South America, Africa, Asia, Australia and parts of Europe—in a variety of habitats from deserts to rainforests, terrestrial, arboreal and even fossorial.
Diet in the wild: Generally eat insects, but the largest are able to eat birds, mice, lizards and even snakes.
Diet at Caldwell Zoo: Crickets, cockroaches, small rodents.
Size: From the size of a fingernail to the size of a dinner plate.
Family: As with all spiders, tarantulas lay eggs.
Status: Depends on species, but IUCN lists many spider populations as decreasing. Many species have not been studied enough to have adequate population numbers.
Did you know? There are about 900 species of tarantulas. Often tarantulas have a rather hairy body, although there are spiders which are not tarantulas that can have some body hairs. All spiders have venom—an aid in capturing prey. There are only a handful of spiders that are harmful to humans.
