This dried specimen of Teredo navalis was extracted from the wood and the calcareous tunnel that originally surrounded it and curled into a circle artificially. The two valves of the shell are the white structures at the anterior end; they are used to dig the tunnel in the wood.

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;" however, they are not worms, but marine bivalve molluscs (phylum Mollusca) in the taxonomic family Teredinidae . The type species is Teredo navalis . [1]

Contents

The tunneling habit of species in the genus inspired the name of the Teredo network tunneling protocol. The submarine HMS Teredo 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.

Diet

Like most marine based bivalves, teredo worms are primarily filter feeders and consume mostly seston, and not wood. [2] Wood supplements their primary diet and is consumed with the assistance of bacteria inside their [gill] cells. [3] However, wood is not a necessary part of their diet and they can live on the surface both of wooden and non-wooden structures. [4]

This photo demonstrates teredo worms do not require wood to survive and can damage non-wooden structures. This photo is of an epoxy-fiber glass vessel. Hole depths were less than 10mm. Remnants of a casing on the surface of the hull appear bottom right. Teredo Worm damage on a non-wooden sailing vessel.jpg

<span class="mw-page-title-main">Shipworm</span> Family of molluscs

The shipworms are marine bivalve molluscs in the family Teredinidae: a group of saltwater clams with long, soft, naked bodies. They are notorious for boring into wood that is immersed in sea water, including such structures as wooden piers, docks and ships; they drill passages by means of a pair of very small shells (“valves”) borne at one end, with which they rasp their way through.

In computer networking, Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network. Unlike similar protocols such as 6to4, it can perform its function even from behind network address translation (NAT) devices such as home routers.

Teredo navalis, commonly called the naval shipworm or turu, is a species of saltwater clam, a marine bivalve mollusc in the family Teredinidae. This species is the type species of the genus Teredo. Like other species in this family, this bivalve is called a shipworm because it resembles a worm in general appearance while at the anterior end it has a small shell with two valves, and it is adept at boring through wood.
