Title: Is there a biological difference between fresh water and salt water fish?
Post by: katieHaylor on 04/09/2018 09:49:44

Hong asks:

What is the biological difference between a fresh and salt water fish? Why can’t some fresh water fish survive in salt water, and vice versa, but some fish like salmon and eels can?

What do you think?
