Thomisidae

Instead of spinning webs to catch prey, crab spiders utilize camouflage. Some crab spiders resemble bird droppings, while others look like fruits, leaves, grass, or flowers. Some crab spiders are capable of changing colors entirely.

When prey approaches, the crab spider attacks and administers a poisonous bite. Crab spider venom is potent enough to render large insects immobile. It is not medically threatening to humans.
