Teredo navalis

Size: to 5 "

This worm-like creature is actually a bivalve mollusk with a greatly reduced shell, which it uses to bore tunnels into wood. They typically spend their entire lives in a tunnel in a single piece of wood. In addition to feeding off the wood, they can also filter feed like ordinary bivalves.

In the age of wooden ships, teredos and other wood-borers were a tremendous problem. In our area, more wood-boring is done by crustaceans than Teredos.
