Question:
__________ is an example of marine wood borer.
__________ is an example of marine wood borer.
Show Hint
Marine wood borers are broadly classified into two groups: molluscans (such as the shipworm Teredo) and crustaceans (such as Limnoria and Sphaeroma).

- Pseudomonas
- Vibrio
- Bacillus
- Limnoria
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Marine wood borers are marine organisms that bore into wooden structures (such as boat hulls, pilings, and jetties), causing structural damage.
Step 2: Detailed Explanation:
Limnoria (commonly known as gribbles) is a genus of small, wood-boring marine isopods (crustaceans).
They feed on the cellulose in submerged wood, creating networks of small tunnels that weaken the timber.
Pseudomonas, Vibrio, and Bacillus are bacterial genera that may participate in surface biodegradation but are not active mechanical wood borers.
Step 3: Final Answer:
Therefore, Limnoria is an example of a marine wood borer.
