Flea Hairs

Some species of fleas, such as the cat flea, have rearward projecting bristle-like hairs that help them to move forward through an animal's fur and keep them from falling out.Ctenocephalides felis is commonly known as the cat flea and Ctenocephalides canis is known as the dog flea. Both are members of the 1,600 species referred to as fleas, order Siphonaptera (“wingless siphon”). These blood-sucking insects can be found worldwide, from the Arctic to the tropics.
