* Mucus: Fish have a protective layer of mucus on their skin. This mucus helps prevent infection and aids in healing.
* Skin Regeneration: Fish have specialized cells called epithelial cells that can rapidly divide and replace damaged tissue. This allows them to quickly heal cuts and abrasions.
* Limited Healing: While fish can heal cuts, the extent of their healing capabilities depends on the severity of the injury. Deep cuts or injuries that damage underlying muscles and bones may be harder to repair.
* Environmental Factors: Water quality, temperature, and the presence of bacteria can all affect a fish's ability to heal.
Essentially, fish have a remarkable ability to repair minor wounds, but they don't possess the same complex healing mechanisms as humans.
