This spider gets its name from its mode of hunting and the speed with which it hunts. They are sometimes referred to as giant crab spiders based on their appearance and size. They are common in areas with warm or tropical climate in different parts of the world.

They have eight eyes, which are placed in rows of four. Males can attain a leg span of up to 12 inches. Their identifying feature is their legs, which are uncharacteristically twisted in a crab like fashion, extending forward from their body. It is mainly found in brown or grey shades with black and white undersides and reddish patches on the mouth parts.

They move quite fast and may shock an individual due to their large size and fast movements. They have flat bodies that help them to crawl under rocks, barks and other hiding places with ease. Their bite is not poisonous but will cause swelling and pain, and they typically feed on insects.

The female can lay a maximum of 200 eggs and guards them with such dedication that it doesn’t leave them for up to 3 weeks even to eat. Other species carry the eggs about as they search for food or shelter. They have a life span of about two years and molt in order to grow. Their discarded shells can sometimes be mistaken for live spiders. These spiders do not build nets and just move around hunting for food and they shelter themselves in barks or under rocks. .
