What shape do pubic lice resemble?

Pubic lice, commonly known as crab lice, resemble the shape of a crab due to their distinctive wide bodies and large claws, which are adapted for gripping hair. This resemblance is a key identifier for them as they have a broader and flatter appearance, unlike other types of lice or insects. Their size is about 1-2 mm in length and they are typically brown or gray in color, further enhancing their crab-like appearance. Understanding this characteristic shape is helpful for identifying these parasites and distinguishing them from other potential pests.
