1. "Wood-eating" Fish:
* Shipworms: These are actually marine mollusks, not fish, but they are commonly called "shipworms" because of their wood-eating habits. They burrow into wood and digest it using bacteria.
* Teredo worms: Similar to shipworms, these are also marine mollusks that feed on wood.
2. Fish That Consume Wood-Derived Food:
* Some species of catfish: Some catfish species, like the wood-eating catfish, consume wood debris that is covered in algae, fungi, and bacteria.
* Some species of carp: Certain carp species will consume wood debris along with their diet of plants and invertebrates.
Important Note: While these fish might consume wood, they don't actually digest the wood itself. Instead, they consume the microorganisms and other organic matter that grow on the wood.
