The Teredo Worm is found in the rotting wood and logs of mangrove swamps in northern Australia. It requires a salt water environment to live. Although it looks like a worm and is called a worm, it is actually a mollusc. The worm is grey in colour, up to 45cm in length and extremely soft and pliable, except for the hard wood-chewing head.

 To find the worm, rotting mangrove logs should be smashed up to expose the channels within the wood. These channels are the areas where the mangrove worm has eaten its way along the rotting soft wood . . .
