Commonly found in vegetated ponds consisting of fresh or brackish water, these long-legged ambush predators spend most of their time in the water waiting for prey. Water scorpions eat a variety of creatures including Daphnia, small tadpoles, fish, backswimmers, and mosquito larvae, using their long specialized front legs to grab them. Water scorpions do not sting, and are harmless to humans. What looks like a long tail or stinger is actually a snorkel that consists of two half cylinders which delivers air to its spiracles, or breathing holes, on the abdomen.
