On average, a huntsman spider's leg-span can reach up to 15 cm (5.9 in), while their bodies measure about 1.8 cm (0.7 in) long. [11] Like most spiders, [12] Sparassidae use venom to immobilize prey.

The spider has a crab-like appearance due to their legs being "laterigrade", at the base so as to be oriented in a horizontal plane rather than a vertical plane. The total leg span of Olios giganteus can be up to 3 inches. [7]
The size of these spiders, combined with the yellow and black banding on the underside of the legs exposed when the spider is in threat pose, give them a fearsome appearance. [1] [4] An experiment was done in 1959 where a Palystes superciliosus was allowed to bite an adult guinea pig on the nose. The guinea pig died within 7 minutes, leading to ...

Young spiders have a yellow-brown cephalothorax, with dark marginal and median stripes. Only after the last molting in the following spring the juveniles assume the typical coloration of the adults. The green coloration is due to the bilin micromatabilin [ 9 ] and its conjugates in haemolymph , interstitial tissues and the yolk of oocytes .
