A flea is a small, wingless insect that is typically brown or reddish-brown in color, with a flat, oval-shaped body and a long, slender tail. It has six legs and a distinctive jumping ability, allowing it to jump long distances to move between hosts. Fleas are external parasites that feed on the blood of mammals and birds, and are often found in the fur of dogs, cats, and other animals.
