Question: will axolotl gills grow back?
Answer: If the tail, a limb, or part of the gills is damaged or removed, they are soon replaced. A leg can be regenerated in 2-3 months. Regeneration is much slower in adult axolotls, and it doesn't occur at all in metamorphosed ones. Axolotls use their feathery gills for respiration, taking oxygen directly from the water.
