Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
Theraphosa apophysis generally resembles Theraphosa blondi, and reaches a similar size. [3] Young T. apophysis spiders have pink shading at the end of each leg, which fades with each moult. [4] T. apophysis has an additional stridulating organ on the coxa of the second leg and thinner femora than T. blondi.
