6.93 Giant Tarantulas. One of the larger species of tarantu- las is the Grammostola mollicoma, whose common name is the Brazilian giant tawny red. A tarantula has two body parts. The anterior part of the body is covered above by a shell, or cara- pace. From a recent article by F. Costa and F. Perez-Miles titled Reproductive Biology of Uruguayan Theraphosids" (The Jour- val of Arachnology, Vol. 30, No. 3, pp. 571-587), we find that the carapace length of the...
