any marine bivalve mollusc such as Teredo, that bores into woodwork by rotary action of the two shell valves and swallows the sawdust, which is then attacked by special enzymes that make possible the digestion of cellulose.
Fifita said the wreck had copper cladding on its hull, which Britain s National Maritime Museum in Greenwich said meant it dated from 1780 to 1850, when such cladding was used to protect against shipworm and marine weeds.
The topics are the Baltic Sea as a unique resource of underwater cultural heritage, other European waters, the Baltic Sea environment, wood as material, wood degraders in the Baltic, the decay process of shipwrecks timbers in the Baltic, the spread of shipworm into the Baltic, and in-situ preservation of a wreck site.
There is lansiao (bull-testicles soup, also called "Soup No 5") in Cebu, crispy kamaru (crickets) in Pampanga, kaleskes (intestines) in Pangasinan, and Palawan's tamilok, which is a shipworm (yes, it's a worm) that is eaten raw and is prepared with vinegar, chopped chilli peppers and onions.
Contributing to the value of the work is a cover photo of a statue of Columbus and myriad drawings, maps, and illustrations, including a match light rifle, native enslavement, smallpox virus, and shipworm.
