How long does it take for an axolotl to regenerate a lost limb?

Axolotls can regenerate lost limbs in approximately 30 to 90 days, depending on factors such as the size of the limb and the age of the axolotl. The regeneration process involves complex biological mechanisms, including the formation of a blastema, which is a mass of cells capable of growth and regeneration. Environmental conditions and overall health can also influence the regeneration time.
