The diversity of the crab spiders family (Thomisidae) is evident in a multitude of shapes and the variety of color patterns on their bodies. This diversity is linked to the variety of habitats to which the spiders of this group have adapted, to their different ways of life, and to their remarkable ability to camouflage. Some of them can even slowly change the color of their bodies so that it better matches the substrate on which they reside.
Most species more or less resemble crabs, as the first pair of legs is longer and directed forward, and they can also move sideways, not only forward and backward. None of the crab spiders spin webs for the purpose of catching prey. Most of them lie in wait for prey in ambush, while some actively hunt it.
The sexes in some genera differ markedly, both in size and coloration. The diversity of the group is also evident in mating. Some species have real 'nuptials' with complex courtship rituals, while in other species the ceremony is short and mating rapid. Females usually carefully guard the egg sacs, but they often die before the spiderlings hatch.
