Tarantulas comprise a group of often hairy and very large arachnids of which approximately 900 species have been identified. Most species of tarantulas are not dangerous to humans, and some species have become popular in the exotic pet trade. Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support. Tarantulas sizes range from as small as a fingernail to as large as a dinner plate when the legs are fully extended.
