| In 1761 the Royal Navy clad the hull of the frigate HMS Alarm with copper sheet to reduce the growth of marine biofouling and prevent attack by the Teredo shipworm. |
| Its independence of moisture, its exemption from the ravages of the teredo, render it much preferable to timber for marine work. |
| Greenheart is the wood used for gates exposed to salt water, as it resists the attack of the teredo in temperate climates. |
| The shell of Xylophaga, 7, is like that of teredo, but the animal has neither pallets nor tube. |
| The latter have remained for years at the bottom of the sea uninjured by teredo, or any destructive crustacea. |
| A ship returning from the tropics brought with it, it is supposed, some tiny little shell-fish, the teredo navalis. |
