Limnoria quadripunctata
Taxonomic Group: Crustaceans-Isopods


Limnoria quadripunctata is a small marine wood-boring isopod, commonly known as a gribble. It was first described from the Netherlands, but is widely distributed throughout the South Pacific, and its native range is currently unknown. It has been introduced to California, where it ranges from La Jolla to Crescent City. It is also considered to be introduced to Europe, the Azores, South Africa, Bermuda and Belize. It prefers temperate climates and marine salinities where it is found boring into wooden surfaces, including wharfs, pilings, docks, and boat hulls. It causes economic damage to port structures and it is considered a pest species in many introduced locations.
