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.
