7 creatures with limb regeneration abilities

Sea Cucumber

Sea cucumbers have the ability to heal wounds and rebuild organs in as little as a week. To divert crabs and turtles, among other predators, they even expel certain organs.

Starfish

By storing nutrients in their limbs, starfish are able to grow back missing limbs and, in certain situations, their complete body from a single lost arm.

Axolotl

Research on human limb regeneration is being conducted on the axolotl, a relative of the salamander, because it has the ability to regenerate skin, limbs, and even its spinal cord.

Salamander

By using a process in which cells migrate to the site of injury to build new tissue, salamanders are able to regenerate back their entire missing tail, including the spinal cord and nerves.

Mexican Tetra

The Mexican tetra fish has varying regeneration powers, with river fish rebuilding tissue and cave-dwelling tetras producing scars, spurring scientific inquiry.

Sharks

Although they are unable to regenerate entire organs, sharks are excellent at developing new teeth several times over the course of their lives, albeit this process might take days or months.
