Tarantula, Portal, Arizona, 1971

Photograph by Paul A. Zahl

Shy, fragile, virtually harmless, tarantulas still can't shake their horror-movie image. Like almost all spiders they are venomous, but they rarely bite people, and there has never been a reliable report of a human death from the venom.

Spiders cannot eat solid food. Instead, they pump digestive fluids into their prey, then suck up the dissolved body parts. A tarantula will sometimes kill a small animal like a snake, frog, or bird, but crickets, beetles, and other insects are more typical prey.
