Water Scorpion Nepa
Water Scorpion Ranatra

How long can you stand without moving? A water scorpion can hang upside down perfectly still for hours just waiting. When an unsuspecting tadpole, fairy shrimp, or insect comes along, the water scorpion lunges forward and grabs it with razor sharp front legs. Its long, thin mouth is inserted into the prey, gradually sucking out the insides, leaving an empty shell behind. The long tail isn't a stinger. It is a snorkel used for breathing. Watch how the tip is held right at the water surface, allowing the water scorpion to breathe and hunt at the same time.
