Silverfish

Silverfish and their close relatives Firebrats are characterized by three long tail-like appendages arising from the tip of the abdomen. They have chewing mouthparts, long antennae and the body is almost always covered with scales. When viewed from the top, silverfish have a carrot-shaped outline. They are usually a steel gray or metallic silver color and are about 1/2 - 3/4 inch (12 - 18 mm) in length. They prefer warm, damp, dark undisturbed areas.
