Question

Name three animals that have a streamlined body.

Answer 1

Hint: A streamlined body is a specified kind of body shape that is tapering towards the ends. This reduces the friction drag between a fluid such as air or water when the object is moving through the fluid. Thus streamlined bodies are of great help to birds to fly in air as it reduces air resistance and also to aquatic animals that helps them to swim easily in water reducing water resistance.

Complete Answer:
- Three animals that have streamlined bodies are fishes, birds and snakes. Presence of this kind of body shape is advantageous for their living.
- For fishes streamlined bodies help them swim in water with the least possible resistance. This helps them in their movement in water which can be either for the search of food or to escape predation.
- Having a streamlined body helps them to swim faster than other body types. Birds also have streamlined bodies that help them fly in air with the least resistance. This also helps them to move from one place to another at much faster speed whenever the need be.
- Snakes are the third kind of organisms that have a streamlined body. This helps them in their fast-paced movement on the ground and also helps them take shelters in holes underground and also to catch prey.

Note: Thus we can see the presence of streamlined bodies are serving to be beneficial for the organisms possessing them. So by evolution these kinds of body shapes have been selected for them that makes their living and survival easier in nature.
