Shipworm This dried specimen of Teredo navalis, and the calcareous tunnel that originally surrounded it and curled into a circle during preservation, were extracted from the wood of a ship. The two valves of the shell are the white structures at the anterior end; they are used to dig the tunnel in the wood.
Shipworms can spread to new wood only when they are in the free-swimming larval stage. [8] Once they attack and bore into the wood, they become imprisoned within it.

Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
No living adult shipworms of this species have been found in Hawaii or in North America. The excavations within the wood are of varying lengths and diameters, and it appears to be the case that the whole of the life cycle of this species of shipworm takes place in mid-ocean, with larvae settling on the timber and reproducing there as the wood ...
