Ligia exotica is commonly known as the Sea Roach. It was first described from shipping docks in Marseilles, France, but is native to the Indo-Pacific and Asia. Introduced populations are found on the East Coast of North America (New Jersey to the Caribbean), the Azores, West Africa, Argentina, and a number of Pacific Islands, including Hawaii.

The "wharf roach," or "sea roach" (Ligiaexotica), is a common isopod often found running around on pier pilings and rocks at high tide. It is a scavenger that feeds on organic matter that it scoops up from rocks and pilings.

This creature superficially resembles a cockroach and has been commonly called the “sea roach.” Like the cockroach, this arthropod is a scavenger. Populations of sea roaches eat tons of beach debris, including decaying plants, algae, dead fish and carrion, and thus are considered to be beneficial organisms.
