Tarantula Killed By Black Widow

Tarantulas
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. Most species of tarantulas are not dangerous to humans, and some species have become popular in the exotic pet trade.
• Overview
Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support. Like other Arachnida a tarantula’s body comprises two main parts, the prosoma (or cephalothorax) and the opisthosoma (or abdomen). The prosoma and opisthosoma are connected by the pedicle, or pregenital somite. This waist-like connecting piece is actually part of the prosoma and allows the opisthosoma to move in a wide range of motion relative to the prosoma.
