Centipedes have one pair of legs per body segment, with the first pair of legs being modified into fangs. Centipedes are generally flattened and have a pair of well developed antennae on the head. Some centipedes have long legs and are capable of running rapidly, and some may grow to be about 6 inches long.
Centipedes have chewing mouthparts. Centipedes prefer to live in moist habitats and during the day occur underneath rocks, logs and other objects in contact with the ground. They are active at night. Centipedes feed on insects and spiders. They kill by grasping prey with their powerful fangs and injecting venom. The fangs are located on the body segment just behind the head.
