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.

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.
It exhibits a multitude of colors, with bright yellowish leg stripes, dark black "femurs", and pink hairs all over its body. As with the rest of the genus Grammostola, the Chaco golden knee has very large fangs, and the carapace (the top of the prosoma) is raised to make room for the large chelicerae. It has rudimentary eyesight, and senses its ...
