Whales are mammals that breathe air and fish draw oxygen from the water. whales have live birth instead of eggs and parent there offspring. whales have skin not scales. whales also have special long teeth which you only see in bottom feeder fish.

And fish have vertical tails that they move side to side to swim, whales have horizontal tails that they move up and down to swim.

Whales have to take in oxygen cuz they are mammels and fish take oxygen from the water through gills also whales can use echo location.
