Which animal has a streamlined body shape and why?

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.

Why do most fish have a streamlined body?

Fishes have streamlined body so that it can reduce friction in water and thus helping the fishes to move easily.

Why do animals such as fish and sharks have streamlined body?

How does it help in movement of animal that flies or swims? A: A streamlined body is a shape of body that reduces resistance when moving. ... Some animals, such as sharks and dolphins, are streamlined so that they have less resistance when swimming in water.

Why do fish and birds have streamlined body?

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.

Why do dolphins have streamlined bodies?

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').

Why fishes are streamlined but most of the microscopic organisms are not?

As with moving through any fluid, friction is created when molecules of the fluid collide with organism. The collision causes drag against moving fish, which is why many fish are streamlined in shape.

Which of the following animals have streamlined body?

Complete answer:

Birds have a streamlined body to make their flight easier through the air. Snakes have a streamlined body to assist them move forward. Some other animals, such as sharks and dolphins, are streamlined so that they have less resistance when swimming in water.

Why fish have streamlined or boat shaped body?

Answer: (i) The streamlined body shape (boat shape) allows the fish to move easily in water. (ii) Fishes cannot survive outside water because fishes have gills which help them to use the oxygen dissolved in water. Gills are unable to absorb atmospheric oxygen, due to which the fish will die when removed out of water.

What do you mean by a streamlined body give two examples of animals having streamlined body explain how a streamlined body helps them?

Examples: Fishes have streamlined body so that they have less resistance when swimming in water. Birds have a streamlined body to make their flight easier through air. Snakes have streamlined body to help them move forward. bolivianouft and 5 more users found this answer helpful.

What does it mean to have a streamlined body?

A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. ... It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object's motion.

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.

Which of the following animals do not have a streamlined body?

Squid and Octopus do not have streamlined type of body.

Why do some animals live in water bodies?

Importance for environment. Aquatic animals play an important role for the environment as well as human's daily usage. The importance of aquatic animals comes from the fact that they are organisms that provide humans with sources such as medicine, food, energy shelter, and raw materials that are used for daily life.

Why do aquatic animals have boat shaped bodies?

(i) The streamlined body shape (boat shape) allows the fish to move easily in water.

How does streamlined shape help fish to swim?

A: Streamlining your body reduces the friction of movement to a minimum thus decreasing overall drag. For fishes having a streamlined body that is smooth helps save energy it would otherwise have to expend swimming.
