According to wikipedia , Sand Spider is a six-eyed spider, found in deserts and other sandy places in southern Africa. Due to its flattened stance and laterigrade legs, it is also sometimes known as the six-eyed crab spider. Studies of its venom have led some to recognize this spider's bite as the most dangerous on record. 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.
