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 is considered to be a difficult tarantula to care for and maintain, and is therefore not recommended for beginners. [4] This is due to their nervous and defensive disposition, as well as high humidity requirements. However, their large size, food-aggressiveness, and fast growth rate make them desirable for more experienced ...
Species belonging to this genus are amongst the relatively small exception of tarantulas that can jump moderate distances as juveniles, with most tarantulas being limited to lunges of 3-4 centimeters. [3] Urticating hairs are distinct to new world tarantulas including the Avicularia that are attached to the spider's cuticle via a stalk. [4]
Like all tarantulas, the horrida's ancestors diverged from a common ancestor with the normal, web-spinning spider perhaps 350 million years ago. This spider is shares its genus to the tiny (1-inch-long (2.5 cm)) b. lennoni , the John Lennon tarantula, and has many traits that imply it is closely related to Theraphosa blondi the Goliath ...
