Sicarius-species-----N.-Larsen--NL96
The six-eyed sand spider (Sicarius hahni) is a medium-sized spider with body measuring 8 to 15 mm and legs spanning up to 50 mm, found in deserts and other sandy places in southern Africa. It is a member of the Sicariidae family; close relatives may be found in both Africa and in South America, and its near cousins, the recluses (Loxosceles), are found worldwide. Due to its flattened stance and laterigrade legs, it is also sometimes known as the six-eyed crab spider. Bites by Sicarius to humans are uncommon; there are no proven cases and only two suspected cases where the culprit was never identified. Sicarius bites have been experimentally shown as lethal to rabbits within 5 to 12 hours. The genus name Sicarius is Latin for 'murderer', from sica, a curved dagger. The species was named after Carl Wilhelm Hahn.

BehaviorEdit

This spider buries itself in the sand and strikes from ambush at prey that wanders too closely. Sand particles adhere to cuticles on its abdomen, thus acting as a natural camouflage if uncovered. If disturbed, it will run a short distance and bury itself again. The six-eyed spider has a poor sense of direction, unlike other species of spiders.

AppearanceEdit

Six Eyes Sand Spider2
The Six Eyed Sand Spider is covered in small hairs, called setae (a stiff hair, bristle or bristle-like process or part of an organism), which serve to hold particles of sand. This provides effective camouflage even when the spider is not buried.

The Six Eyed Sand Spider has a body length up to 0.6 inches (15 millimetres) and the width across the legs is about 2 inches (50 millimetres). Most species are reddish-brown to yellow in colour without any distinct patterns. Six Eyed Sand Spiders often camouflage themselves with sand particles wedged between body hairs in order to blend into the background of their specific habitat. The Six Eyed Sand Spiders are shy and secretive, however, they will bite when accidentally contacted.

VenomEdit

Toxicology studies have demonstrated that the venom is particularly potent, with a powerful hemolytic/necrotoxic effect, causing blood vessel leakage, thinning of the blood and tissue destruction. Sicarius bite treatment should be directed, as with all cytotoxic bites, at prevention of secondary infection and combating Disseminated intravascular coagulation (DIC) if it develops. No anti-venom exists for it.
