Water Scorpion

Laccotrephes sp.

Using a long tube, or siphon, as a snorkel to access air, the water scorpion sits on the bottom of a pond and waits for prey to come by. It grabs prey with its forelegs. Through a straw-like mouthpart, the water scorpion injects the prey with saliva to liquefy it. Then it sucks up dinner.
