Crabs

Crabs are referred to as such because of their resemblance to the crustaceans of the same name, though on a much smaller scale.

Crabs are incredibly common with roughly 3 million people affected yearly in the U.S. alone. One reason for this is the ease with which they are transmitted. While they are not transmitted via casual contact like hugs or handshakes, they can easily pass from person to person via sexual contact. It is also possible for crabs to live in any coarse hair on the body including body hair, facial hair, eyelashes, and eyebrows.
