They bore into submerged [[wood]], and bacteria in a special organ called the gland of Deshayes enable them to digest [[cellulose]]. The shipworms belong to several [[genus|genera]] of which ''[[Teredo]]'' is the most commonly mentioned.<br /> <br /> Shipworms have slender worm-like forms, but possess the characteristic structures of [[bivalve]]s. The valves of the [[Animal shell|shell]] are small separate parts located at the anterior end of the worm, used for excavating the burrow. Shipworms do great amounts of damage to wooden hulls and marine piling, and have been the subject of much study to find methods to avoid their attacks.<br /> <br /> In the early 1800s, the behaviour and anatomy of the shipworm inspired the great British engineer Sir [[Marc Brunel]]. Based on his observations of how the shipworm's valves simultaneously enable it to tunnel through wood and protect it from being crushed by the swelling timber, Brunel designed an ingenious modular iron tunnelling framework which enabled workers to successfully tunnel through the highly unstable river bed beneath the Thames, resulting in the first successful large tunnel ever built under a navigable river.<br /> <br /> [[da:Pæleorm]]<br /> [[de:Schiffbohrwurm]]<br /> [[ja:フナクイムシ]]<br /> [[nl:Paalworm]]<br /> <br /> [[Category:Molluscs]]</div>
