Why whales do not live in fresh water?

Answer 1

Whales don't live in fresh water because fresh water is too shallow and lacks the large quantities of prey they require to stay alive.

Some dolphins, which are small versions of whales, live in fresh water. Whales have been known to enter rivers, but, rivers do not have enough food to feed whales so they leave fairly soon.

During World War 2 a number of rivers in the United State had anti submarine mines at the river mouth where the rivers empty into the ocean. Occasionally a whale would set one off and get blown up. That is how we know whales swim in rivers.
