Teredo (bivalve)

Teredo is a genus of highly modified saltwater clams which bore in wood and live within the tunnels they create. They are commonly known as "shipworms," and are marine bivalve molluscs in the taxonomic family Teredinidae. The type species is Teredo navalis.

Because it is a tunneling genus, Teredo was chosen as the namesake of the Teredo network tunneling protocol. HMS Teredo, a submarine, may also have been named after this genus, which works invisibly, below the surface, and can be very damaging to marine installations made of wood.
