Chelura terebrans
Taxonomic Group: Crustaceans-Amphipods


Chelura terebrans is a marine wood-boring amphipod, often associated with isopods of the genus Limnoria. It has a broad global distribution being found from 18 – 61°N in the northern hemisphere and 30 – 44°S in the southern hemisphere. It is thought to be native to Europe with introduced populations on the East and West coasts of North America, Hong Kong, South Africa and New Zealand. It was most likely transported to many locations within the hulls of wooden ships. As a wood-boring pest, it has economic impacts by destroying wooden maritime structures.
