Why do fish and birds have streamlined body
Dear Student
Fish and birds have a streamlined body to experience minimum resistance when travelling through fluids (water and air respectively) which makes it easier for them to move with great speeds.
in other words
Birds and fishes have streamlined body because streamlined body helps to reduce the friction between the body and the fluid (air or water). Thus, it helps them to move easily and quickly in air and water respectively.
