Limnoria saseboensis

Limnoria saseboensis is a species of marine crustacean belonging to the genus Limnoria, commonly known as gribbles. Gribbles are isopods, a diverse group of crustaceans found in marine, freshwater, and terrestrial environments.12

Limnoria saseboensis specifically is found on the Atlantic coast of the southeastern United States and on the coast of Japan. These small crustaceans, typically growing up to 5 mm in length, feed on algae and wood, including submerged structures like docks and wharves. Some species within the Limnoria genus can even bore into wood treated with creosote, a chemical that deters most wood-boring invertebrates.1
