Extraordinary Animals That Can Regrow Limbs

May 2024 · 1 minute read

Alternatively known as crayfish, crawdad, and more, the names all refer to the same species. The crawfish is such a prevalent species because it's so adaptable. Anywhere that has fresh water and reliable food, you will find crawfish, and you will find a lot of them. According to Britannica, there are approximately 500 variations of crawfish around the world, with over half of them residing in North America.

While they've become a staple of southern cooking, they also have the ability to regenerate their claws, according to a scientific study from the National Library of Medicine. Noted for being one of the largest parts of their body, their claws are vital to their survival, and they use them for both defense against predators and for catching food themselves. So, naturally, if they lost one, it would be more than a little bothersome to a poor little crawdad. Nature has them covered, though, because those claws regenerate. If you happen to see a crawdad with one big claw and one small claw, that's because it's in the process of regeneration. This holds true for all crustaceans — crabs, lobsters, the whole lot of them.
