Untreated wood piles and poles in coastal waters are attacked rapidly by which organisms?

Explanation:
Submerged timber in coastal waters is attacked by marine borers—organisms adapted to living in saltwater that bore into wood. These include shipworms and related creatures that tunnel through piles and poles, causing rapid structural deterioration in untreated timber. Terrestrial pests like termites and carpenter ants require dry wood with access to air or soil, so they don’t target wood that stays underwater. Fungi can rot wood too, but in fully submerged seawater the primary culprits are marine borers, which are specifically adapted to the aquatic environment and drive the quick damage seen in coastal installations.
