'''Shipworms''' are not worms at all, but rather a group of unusual saltwater clams with very reduced shells, notorious for boring into (and eventually destroying) wooden structures which are immersed in sea water, including piers, docks and wooden ships. Sometimes called "termites of the sea", they are marine bivalve molluscs (Eulamellibranchiata) in the family '''Teredinidae'''.

They bore into submerged wood, and bacteria in a special organ called the gland of Deshayes enable them to digest cellulose. The excavated burrow is usually lined with a calcareous tube.

The shipworms belong to several genera, of which ''Teredo'' is the most commonly mentioned. The best known species is ''Teredo navalis''. Historically, ''Teredo'' concentrations in the Caribbean Sea have been substantially higher than in most other salt water bodies.

Shipworms have slender worm-like forms, but nonetheless possess the characteristic structures of bivalves. The valves of the shell of shipworms are small separate parts located at the anterior end of the worm, used for excavating the burrow. Shipworms greatly damage wooden hulls and marine piling, and have been the subject of much study to find methods to avoid their attacks.

In the early 1800s, the behavior and anatomy of the shipworm inspired the great British engineer 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 - a tunnelling shield - which enabled workers to successfully tunnel through the highly unstable river bed beneath the Thames. The Thames Tunnel was the first successful large tunnel ever built under a navigable river.

'''Shipworms''' are not worms at all, but rather a group of unusual saltwater clams with very reduced shells, notorious for boring into (and eventually destroying) wooden structures which are immersed in sea water, including piers, docks and wooden ships. Sometimes called "termites of the sea", they are marine [[bivalve]] [[mollusc]]s ([[Eulamellibranchiata]]) in the family '''Teredinidae'''.

They bore into submerged [[wood]], and bacteria in a special organ called the gland of [[Gérard Paul Deshayes|Deshayes]] enable them to digest [[cellulose]]. The excavated burrow is usually lined with a calcareous tube.

The shipworms belong to several [[genus|genera]], of which ''[[Teredo (genus)|Teredo]]'' is the most commonly mentioned. The best known species is ''Teredo navalis''. Historically, ''Teredo'' concentrations in the [[Caribbean Sea]] have been substantially higher than in most other salt water bodies.

Shipworms have slender worm-like forms, but nonetheless possess the characteristic structures of [[bivalve]]s. The valves of the [[Animal shell|shell]] of shipworms are small separate parts located at the anterior end of the worm, used for excavating the burrow. Shipworms greatly damage wooden hulls and marine piling, and have been the subject of much study to find methods to avoid their attacks.

In the early 1800s, the behaviour and anatomy of the shipworm inspired the great British [[engineer]] [[Marc Isambard Brunel|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 - a [[tunnelling shield]] - which enabled workers to successfully tunnel through the highly unstable river bed beneath the Thames. The [[Thames Tunnel]] was the first successful large tunnel ever built under a navigable river.
