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.
polythalamius was shown to be comprised nearly entirely of sulfur-oxidizing chemoautotrophic (thioautotrophic) bacteria (Distel et al., 2017) rather than cellulolytic symbionts, as observed in other shipworm species (Distel et al., 1991, 2002; Luyten et al., 2006; O'Connor et al., 2014).
As industry explores deeper sea depths, this affects the design and material selection of cables, with challenges such as UV stability, marine growth, microbial attack and even the burrowing Teredo Navalis Shipworm to be addressed.
did so eat the timbers as that we greatly feared they would undoe us by gnawing through the ships side." (36) Presumably, Davis conflates two kinds of verminous threats: the dreaded shipworm, teredo navalis (actually a species of vermiform clam) that destroyed wood, and larvae from various insects that devastated food stores.
A front formed by the junction of frigid polar and warmer waters as well as a strong current circling the continent may block tiny shipworm youngsters from moving in, says Thomas Dahlgren of Uni Research, the University of Bergen's partner research company in Norway.
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.
