What animal can grow a new head?

“And if you think about it, Hydractinia can grow a new head and, although we cannot as adults, we can do that as embryos when we make our own head. So it is possible that this ability to do so is switched off in human adults and in Hydractinia it’s not.”

Can an axolotl regrow its head?

They can regenerate the front portion of their brain, called the telencephalon. Axolotls are able to achieve this sort of regeneration because they react to injuries in an entirely different way than humans.

The damaged cells will die off and the limb will regenerate through cell division, which creates new tissue. Single-celled organisms however cannot utilise this strategy, as they only comprise a single cell — hence upon significant damage, they usually die.

What animal can grow new limbs?

Small reptiles, like lizards, geckos and iguanas, are famous for being able to sprout new limbs if they lose a body part, like a leg or a tail. The regenerated limb usually isn’t exactly the same as the original, but it’s enough to give the critter a new leg up on survival.
