Wood Borers
Wood Borers
animals that bore passages in wood that is exposed to the sea. They belong to the classes Bivalvia (for example, the genera Teredo and Bankid) and Crustacea (the genera Limnoria and Chelura). Of the approximately 200 known species of wood borers, about ten are found in the seas of the USSR. The greatest damage to wooden ships and to port and other offshore structures is done by mollusks. Crustaceans destroy only the surface of wood. Some colonies of wood borers include both mollusks and crustaceans. Control measures include transferring vessels temporarily to fresh water and treating the wood with substances that are poisonous to wood borers.
