Which fish can regenerate lost body parts?

Regeneration is a biological process where an organism can regrow or repair damaged body parts. While many animals, including humans, have some ability to regenerate, certain species of fish are known for their remarkable regenerative abilities.

One fish that is well-known for its regenerative abilities is the axolotl, which is a type of salamander. Axolotls are capable of regenerating limbs, spinal cords, heart tissue, and even parts of their brain. However, if we focus on fish only, then one species that stands out for its regenerative abilities is the zebrafish (Danio rerio).

Zebrafish have the ability to regenerate a wide range of tissues, including their fins, scales, spinal cord, and heart. They can even regenerate parts of their brain and retina. Scientists have been studying zebrafish for decades to understand the genetic and molecular mechanisms behind their regenerative abilities, with the hope of one day applying this knowledge to human regenerative medicine.
