[L. terēdo, ad. Gr. τερηδών a wood-gnawing worm, f. τερ-, root of τείρειν to rub hard, wear away, bore.]
1. Zool. A genus of lamellibranch boring molluscs; esp. the ship-worm, T. navalis, well known for its destruction of submerged timbers in ships, piers, sea-dikes, etc. by boring into the wood.
In accordance with the etymology, the name was formerly applied vaguely to any species of worm or larva that wears its way into wood; the ship-worm was at first supposed to be a worm, and was only in 1733 recognized as a mollusc.
