What do you think a louse looks like?

A louse is a small, parasitic insect that feeds on the blood of its host. It has a flat, elongated body that is usually between 1 and 3 millimeters in length. Its color can range from white to gray or even black. It has six legs, each with a claw-like structure at the end, that it uses to cling to its host. Its head is round and has two antennae and two eyes. Its mouthparts are adapted for piercing and sucking blood.

Lice have a hard exoskeleton that protects them from their environment. They also have a special adaptation that allows them to move quickly through the host's hair. They reproduce by laying eggs, called nits, which attach to the base of the hair shaft. The nits are often white or yellow in color and are difficult to remove.
