The identity of Arctic catfish’s grandfather is not simple. It is said that he is a “big fish”. In fact, catfish itself is not dirty. People say it is dirty because catfish may live in relatively dirty places. Catfish are even found in smelly ditches in some places. Moreover, the food that catfish eats may also be relatively dirty, and sometimes even rotten food.
Actually, in the catfish’s diet, carrion is not the main food. It only eats carrion because it has a wide range of feeding habits. In the diet we often eat Among animals, crabs and crayfish are typical scavengers.
