A new species of shipworm was found in the bottom of the Philippine River this week as introduced by an international group of scientists in Proceedings of the Royal Society B.
It has milky texture similar to tamilok (shipworm), kuhol (snail) or shellfish.
This difference compares with previously observed intraspecies variations of 0.0%--1.7% among specimens within 4 shipworm species (Bankia carinata, Lyrodus pedicellatus, Teredothyra dominicensis, and Neoteredo norvagica).
As with any wood hull used in tropical waters, a skin coat of fiberglass would be necessary to guard against water intrusion as well as against the destructive Teredo navalis (shipworm.) Since this boat would not live in the water full time, worms would be less of an issue, but it was important to add glass to build a super fair surface for the finished appearance and paint.
Researchers also discovered a sulfur-eating giant shipworm that lives at the bottom of muddy lagoons:
Those on the port side were in excellent condition, while their opposite numbers on the starboard side were more exposed and severely attacked by shipworm. A hull segment, possibly detached from the rest of the articulated remains, lay to the north of the port frames.
The Guerrero was known to have a copper-covered hull, which was helpful for boosting speed and reducing shipworm damage but relatively uncommon because of the cost.
French engineer Sir Marc Brunei (1769-1849) invented the caisson, a structure that enables underwater construction, after observing the naval shipworm, a saltwater clam whose valves allow it to bore through wooden ships without being crushed when newly exposed layers of wood absorb ambient water and swell.
