The brown water scorpion can be found in (They often hang suspended from the surface too) ponds throughout North America. In order to breath, the Brown Water Scorpion stretches its' breathing tube from its abdomen to the water's surface. This ability allows the scorpion to remain unnoticed while tracking it's prey, which consists of other insects, tadpoles, small fish and salamanders. The scorpion can also remain motionless for up to 7 minutes before attacking it's prey. The Brown Water Scorpion has a sharp, strong, piercing beak that punctures the skin of the prey, causing it to become numb and immobile.
