Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.[5] 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 pedicel, or pregenital somite. This waist-like connecting piece is actually part of the prosoma and gives the opisthosoma a wide range of motion relative to the prosoma.
