The streamline shape of a fish has lower friction. Also, vortices form from the movement of the tail which save energy when swimming
to reduce friction in water
Some adaptive features of fish are:1)The fishes have fins which help them to swim in water and maintain the body balance.2)They have a tail which helps them to change directions by swimming.3)They have a streamline body shape which them to move through the water.4)They have gills which helps them to breathe the dissolved oxygen in water.By:Artika sharma
it helps in reducing resistance in water

beak- pointed and streamline for swimming and razor sharp for catching fish

The body temperature of a fish swimming around in water that is 60 degrees would be 60 degrees also. This is because fish, unlike mammals, are coldblooded; they do not waste energy keeping their body temperature constant. Their body temperature would match that of the water around them.
These types of fish alway use MUCUS to cover their body, and to help reduce friction.
The scales on the fish body helps it to reduce water loss.
It could mean that you have had a bad encounter with a fish, or a body of water before.
Fish adapt to their environment by having a streamline body to cut through the water and they have gills to help them breathe under water. Some fish are even camouflage to disguise them underwater.
Fish body is of boat shape to balance itself in the water nature have given swimming bladders for fish.
