Rare fish have the ability to regenerate their feet

A rare species of fish, called "water salamander Axolotl", is very much concerned by scientists not only because of "beautiful face with gentle smile" but also because of its quite special ability.

As relatives of tiger tigers, Axolotl sometimes has a body longer than 30cm, but their average size is usually about 10-15cm, and they can live for more than 15 years. Despite his cute face, Axolotl salamanders were dubbed assassins in his habitat, deep pools or deep canals in Mexico.

Axolotl is almost completely extinct because of the dense pollution in the waters where they live. Another reason that this smiley fish has always been included in the annual list of the International Union for Conservation of Nature (IUCN) is that this fish meat tastes very good and special.

Not only because of its cute face, Axolotl salamanders also have the ability to regenerate new legs when cut, and recreate internal organs and part of the brain thanks to their immune system.

Scientists think this fish is the key to opening hope for regenerating limbs in humans.
