Curved claws on its front legs and a long tail-like tube gives this insect the sinister look of a deadly scorpion. Though not a real scorpion, this creature can inject venom into victims, just like its namesake. This bug is only a menace to small prey, but it can still give humans a painful poke with its pointed beak.
Seize the Prey: This killer insect uses its front pair of legs more like arms. The claws on the tips act like wrists, so the water scorpion can reach out and grab onto prey, even fast-swimming fish.
Hanging Out: When the water scorpion hangs onto the stem of an aquatic plant, its brown body looks like a leaf. If a small fish swims within range of the insect’s claws, it strikes, seemingly out of nowhere, to make the kill.
Under Pressure: Special organs in the water scorpion’s body measure the water pressure around it. This insect uses this depth gauge to judge whether to go up or down.
Can’t Swim: As its name implies, the water scorpion spends its entire life in water. This insect cannot swim, however, and can only walk along the bottom or scramble among the leaves of plants growing there.
- The water scorpion is an ambush hunter. It clings to stems and branches under the water and waits for prey to swim by.
- A small fish comes within range, and the scorpion goes for it. The insect grabs its prey with its clawed front legs and spears the victim’s flesh with its hollow, pointed beak.
- The insect injects toxic enzymes into the fish’s body, which dissolve the victim’s insides. The water scorpion slurps up this meal through the beak, using it like a straw.
