Atrax sutherlandi

Atrax sutherlandi is a species of Australian funnel-web spider found in forests on the far southern coast of New South Wales and in eastern Victoria. It was named after Struan Sutherland, whose work resulted in a successful funnel-web spider antivenom.^[2]

Binomial name
Atrax sutherlandi Gray, 2010[1]

Normally, A. sutherlandi has a glossy black back and chelicerae ("fangs"), as well as a deep-brown or plum-coloured underbelly. An adult grows to a length of 2 inches (5 cm). A report in 2015 described an unusual individual with a blood-red belly and chelicerae.^[3] Unlike its close relative the Sydney funnel web that lives in urban areas, A. sutherlandi commonly resides in remote areas, thus posing little danger to the public.^[4]

Due to the niche microhabitat of the Atrax sutherlandi, species divergence can easily occur when there is minor change in the environment. ^[5]
