Grammostola grossa is a terrestrial bird spider. It hides under roots, pieces of bark, stones or fallen leaves. In colder months and during moulting and brood care, it retreats into living burrows, which it lines with spider silk. [6] Habitat changes by humans due to livestock, agriculture and timber farming have allowed this species to spread.
Grammostola is a genus of South American tarantulas that was first described in text by Eugène Louis Simon in 1892. [5] These medium- to large-sized spiders are native to tropical South America, and are usually brown in color, with pinkish or orangish-red hairs.

The Chilean rose tarantula (Grammostola rosea), also known as the rose hair tarantula, the Chilean fire tarantula, or the Chilean red-haired tarantula (depending on the color morph), is probably the most common species of tarantula available in American and European pet stores today, due to the large number of wild-caught specimens exported cheaply from their native Chile into the pet trade.
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".
There are seven different types of urticating hair known in tarantulas, varying in size and shape, particularly the distribution of barbs. [11] Type I (0.2–0.6 mm) Type II (0.5–1.5 mm) Type III (0.3–1.2 mm) Type IV (0.06–0.2 mm) Type V; Type VI; Type VII; Each type of urticating hair is believed to target different enemies.
Grammostola mechanotoxin #4 (GsMTx-4, GsMTx4, GsMTx-IV), also known as M-theraphotoxin-Gr1a (M-TRTX-Gr1a), is a neurotoxin isolated from the venom of the spider Chilean rose tarantula Grammostola spatulate (or Grammostola rosea). [1] This amphiphilic peptide, which consists of 35 amino acids, belongs to the inhibitory cysteine knot (ICK ...
They thrive in environments that mimic the tropics, with a temperature from 70 to 80 °F (21 to 27 °C) and a relative humidity of 70% to 85%. The height of their enclosure is more important than floor space, preferring 14 inches (360 mm) of height and at least 7 to 8 inches (180 to 200 mm) of floor space.
