How do naked fish protect their bodies?

By secreting a mucoprotein slime coating over their skin which protects against invasive bacteria, parasites, and fungus. Also, scale-less fish have a quite tough outer skin composed of fibrous connective tissue.

Hi Marco,

Thanks for the question. I would think that the skin on scale-less or "naked" fish would be sufficiently tough in order to protect against abrasion and other mechanical damage.

I hope this helps. Please let me know if you have more questions. Thanks Jeff
