Crab Lice Definition & Overview

Definition

Crabs, or pubic lice, are tiny, barely visible parasites (scientific name Pthirus pubis ) that live in the pubic area and cause itching. ("Lice" is plural; the singular is "louse"). Pubic lice are commonly called crabs because they are shorter and rounder than head and body lice, making them resemble crabs. They are usually found in the pubic hair, but can also be found in other body areas with short hair (eg, eyelashes, eyebrows, armpits, mustache).
