Can a fish walk like a man give a reason?

Fish cannot walk like a man because they are anatomically and physiologically adapted for swimming rather than walking. Their bodies are designed with fins instead of limbs, and they lack the skeletal structure necessary to support weight on land. While some fish, like mudskippers, can move on land for short distances using their fins, they do not walk in the same way humans do. Thus, the fundamental differences in their Biology prevent them from walking like a man.
