[7] As most in the Mygalomorphae infraorder, they have robust bodies, with a glossy dark colouration in their carapace and legs, and a grey opisthosoma.

[7] They are usually found in burrows with little silk lining, under rocks or logs, with their aptly named funnel-like webs.

After extensive studies, researches have found that there are many geographical and genetic differences that have occurred due to micro-habitat distributions.

The assumption has been made that the species of Atrax have experienced a shift in genetic structure due to the niches that they inhabit.

Habitats are not the only factor to this divergence; researchers have also noted the climatic events, prey availability, and natural occurrence of biodiversity.
