This spider is unique in its ability to camouflage. It not only buries itself in the sand, but even above ground it looks like sand—until you see its crab-like legs scurrying. It has an exoskeleton with bristly hair-like structures that trap sand so the spider is coated in sand at all times.

It rarely bites humans, but its venom is powerful, able to kill a rabbit in a few hours. There are no recorded human fatalities from its bite. Its venom causes blood vessels to leak, tissues to break down, and eventually organ failure.
