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.
