They are distinguished from true spiders by their two pairs of book lungs, vertically oriented chelicerae, and urticating setae. However, like all members of Psalmopoeus, P. irminia lack these urticating hairs but make up for it by having stronger venom compared to other New World tarantulas.
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".
Urticating hairs or urticating bristles are one of the primary defense mechanisms used by numerous plants, almost all New World tarantulas, and various lepidopteran caterpillars. Urtica is Latin for "nettle" (stinging nettles are in the genus Urtica ), and bristles that urticate are characteristic of this type of plant, and many other plants in ...

Although it has hairy legs, this tarantula is an Old World species and does not have urticating hairs on its abdomen. (Urticating hairs are hairs found in most new world species (those from North and South America) that can be shed in defence, they are barbed and may cause severe itching.) It also has a leg span which may reach 8 inches (20 cm).
Although like most new world tarantulas it possesses urticating hairs, if provoked, they would much rather flee than attack. Their venom is not as irritating as many other species of tarantulas. The Brazilian black is a slow grower, taking up to eight years to reach maturity, reaching up to 18 cm (7 in).
The species is one of the largest tarantulas found in the United States, as it commonly reaches a leg span of 5 inches at full maturity with some females reaching a 6-inch span. Like most Aphonopelma species, it has a very slow growth rate and lives for several years before maturing. As in most tarantulas, females are massive as compared to the ...
[7] [8] When disturbed, like most other tarantulas, A. hentzi maneuvers itself to a stance on its hind legs and raises its front legs in a threatening manner. Additionally, A. hentzi and most other tarantulas found in the Americas have small, coarse, brown or black urticating hairs on their abdomens that they kick in the direction of whatever ...
