The Goliath birdeater (Theraphosa blondi) belongs to the tarantula family Theraphosidae. Found in northern South America , it is the largest spider in the world by mass (175 g (6.2 oz)) and body length (up to 13 cm (5.1 in)), and second to the giant huntsman spider by leg span. [ 1 ]
The bite from an Eastern tarantula is not fatal to a human, but can cause up to six hours of vomiting.The venom can cause death to a dog or cat within thirty minutes. [3] [8]In May 2010 a scientist living near Cooktown, Queensland, was bitten on her right index finger and experienced symptoms never reported before in research literature.
Ironically, the term "bird-eater" is more typically applied to the common names of large terrestrial species of tarantulas, such as the Goliath birdeater (Theraphosa blondi), the burgundy Goliath bird eater (Theraphosa stirmi), and the Brazilian salmon pink bird-eating tarantula (Lasiodora parahybana).
Theraphosa stirmi is a species of tarantula belonging to the family Theraphosidae. [1] It is known as the burgundy goliath bird eater. [2] Distribution

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".
Others, such as those of the Brazilian giant white knee tarantula (Acanthoscurria geniculata), are moderately irritating. Still others, such as the Goliath birdeater (Theraphosa blondi), are far more severe. These bristles can result in painful rashes, and have been likened to sharp shards of fiberglass.
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 ...
