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 ]
Linnaeus' name Avicularia is derived from the Latin avicula, meaning "little bird", with the suffix -aria, which is the Latin female singular form of -arius, meaning "pertaining to." This refers to a 1705 illustration by Maria Sibylla Merian, showing a tarantula that appears to be of this genus feeding on a bird. [7]
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 ...
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.

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.
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 ...
This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the "primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this ...
