What animals have a streamlined shape?

- 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.

Which animal has a streamlined body for ease of movement?

For example, fishes have streamlined bodies to help them while swimming in the water, birds have a streamlined body to help them while flying in the air, snakes also have a streamlined body which helps them in their faster movement.

How does a streamlined shape reduce air resistance?

STREAMLINING. When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down. ... designed with curved and sloping surfaces to cut through the air and reduce drag. This helps them to move faster and use less fuel.

What is the shape of that birds have which reduces the air resistance?

The bodies of all flying birds are shaped like teardrops. The streamlining is achieved by specially arranged feathers that reduce the friction that would otherwise act as a drag against the forward-moving body.

Does Dolphin have a streamlined body?

Scientists have known for some time that dolphins have evolved streamlined bodies which help them reduce the pressure of water against their skin (known as the 'form drag') as well as reducing friction (or 'friction drag').

Do penguins have a streamlined body?

Penguins have strong wings and strong pectoral muscles to power them. Their bodies are streamlined as if for flight, so they still cut cleanly through the water. ... In fact, penguins are the only birds that are unable to fold their wings.

Does frog have streamlined body?

Most frogs and some toads are excellent swimmers. They are helped by their powerful hind legs, webbed feet, and flattened, streamlined body. Frogs and toads swim in a similar style as people doing the breaststroke.

What is streamlined body shape?

A streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. ... The streamlined shaped body experiences minimum resistance when travelling through water or air. It helps to reduce friction.

How did the streamlined shape of animals help humans *?

A streamlined body is one which is pointed at the ends and broad in the middle. When such a body travels through a fluid or gaseous medium it exhibits minimum friction or resistance. A body shape which is streamlined helps cut against the friction created by the medium around the moving body. 2.

How does streamlined shape reduce drag?

Answer: With a streamlined shape, the area of the body that pushes air/water becomes very small. It kind of pierces through the air/water because of the small area that is pushes the air/water while traveling through it. So the air/water that needs to be pushed reduces which means less air/water to push.

Why does streamlined shape reduce friction?

It reduces the drag. It is the air/water resistance offered when you travel through it. With a streamlined shape, the area of the body that pushes air/water becomes very small. ... This is how making a body streamlined helps cut through the drag.

How does streamlined shape reduce friction?

Air also produces a drag force on the objects that travel through it. Water creates more drag force than air. ... When the body is streamlined, this area is reduced to a very small amount. Hence, the drag force oppose the motion of the body is small allowing the body to move without much friction.

Why can't penguins and ostriches fly?

Ostriches, emus, cassowaries, rheas, and kiwis can't fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can't possibly lift their heavy bodies off the ground.

Why do birds and fishes have special shapes?

Ans:Birds have streamlined body so as to reduce the air resistance during flying. Whereas fishes have streamlined body so as to reduce friction in water and help them to move faster.

What is the shape of a bird's body?

Boat shaped Body

All birds have a boat-shaped body. Boat shaped body helps a bird while flying.
