Tarantula

Tarantulas comprise a group of often hairy and very large arachnids belonging to the Theraphosidae family of spiders, of which approximately 900 species have been identified. This article only describes members of Theraphosidae, although some other members of the same suborder are commonly referred to as "tarantulas". Most species of tarantulas are not dangerous to humans, and some species have become popular in the exotic pet trade.
