Sphaeroma terebrans is a mangrove-boring isopod that was first documented in the United States as early as 1897. It is 8–10 millimetres (0.31–0.39 in) long and is thought to have been introduced by wooden-hulled ships. The isopod is found throughout the Gulf of Mexico mainly in mangrove swamps of Louisiana and Florida. S.
