They are actually not woodworms at all but mollusks (like a clam or oyster), and they are in the same family as the mysterious shipworm. The creature, which comes straight out of the movie “alien”, has been known to exist for 200 years, but no living specimen was found […] The eating comes at the end of the video. Researchers from the University of the Philippines, Northeastern University, Drexel University and University of Utah found the new genus and species off the coast of Balayan Bay in the province of Batangas, Philippines. Genera within the family Teridinidae include:[8], Shipworms greatly damage wooden hulls and marine piling, and have been the subject of much study to find methods to avoid their attacks. A genus of long, slender, wormlike bivalve mollusks which bore into submerged wood, such as the piles of wharves, bottoms of ships, etc. The shipworm is a not actually a worm at all, but a bivalve -- like mussels and clams -- and has its own brittle, tusk-like shell. Removed from its burrow, the fully grown teredo ranges from several centimetres to about a metre in length, depending on the species. The case of the shipworm is not just the home of the black slimy worm. Researchers from the University of the Philippines, Northeastern University, Drexel University and University of Utah found the new genus and species off the coast of Balayan Bay in the province of Batangas, Philippines. Scientists have found live specimens of the rare giant shipworm for the first time, in the Philippines. Shipworm species comprise several genera, of which Teredo is the most commonly mentioned. In a letter from the Navy Board to the Admiralty dated 31 August 1763 it was written "that so long as copper plates can be kept upon the bottom, the planks will be thereby entirely secured from the effects of the worm.

Shipworm species comprise several genera, of which Teredo is the most commonly mentioned. If the animal is alarmed, it withdraws the siphons and the pallets protectively block the opening of the tunnel. 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—the very first tunnelling shield—which enabled workers to tunnel successfully through the highly unstable river bed beneath the Thames. shipworm or teredo tĕrē´dō , marine bivalve mollusk of the family Teredinidae, specialized for boring in wood. There is a great story behind the name “Tamilok” which dates back to WW2 when two American GI’s observed the local Filipinos harvesting the woodworm, prompting one to yell to the other “Tommy, look!”.

Shipworms harbor bacteria in their gills that produce a suite of enzymes that break down cellulose from wood. Tamilokus mabinia. More recently, the endosymbionts that are found in the gills have been subject to study the bioconversion of cellulose for fuel energy research.[7].
