The longest leg (the fourth) in a male had a total length of 110 mm (4.3 in). Coloration of these heavy-bodied spiders varies from rusty brown or rich burgundy-brown to dark brown, with reddish setae on legs and abdomen and white lines on the legs. Adult males lack mating spurs or tibial apophyses.

The Goliath birdeater (Theraphosa blondi) is reputed to be an avivore (hence the name), but it rarely preys on birds. [5] [6] However, other species of spider have been observed to consume birds that they capture; large orb-weaving spiders, such as the golden orbweavers, have been observed to consume small birds such as mannikin and other finches.
