There are many kinds of freshwater polka-dot raccoons, but wild freshwater polka-dot raccoons are very rare. Its head looks u-shaped, not round. This is a unique genetic mutation. When caught in the wild, they were labeled with a high price of100000 dollars. Although more and more artificial breeding techniques make the price of this fish lower, it can never be compared with wild fish. Because of head deformity, they can't catch shellfish as food, so they lose the ability to survive in the wild and can only survive in captivity.
