Complete answer: A streamlined body provides a smooth surface to the aquatic animal's body which reduces resistance in the water by reducing friction and makes movement easy. Minimum resistance in water increases the speed of the movement, organisms move at a faster speed.

What is the function of streamlined body?
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.
What is a streamlined body and how is it useful to fish?
Fishes have streamlined body so that it can reduce friction in water and thus helping the fishes to move easily.
What are aquatic animals that have a streamlined body?
- 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 fishes have streamlined bodies?
Answer: Fishes are streamlined because the streamlined shape helps them move through the water with the least of resistance.
How does a streamlined body helps a fish to move in water class 6?
The streamlined shape helps the fish to move in water. The skeleton of the fish is covered with muscles which make the front part of the body to curve to one side and the tail part swings towards the opposite side. This makes a jerk and pushes the body forward. In this way, it moves in the water.
Why do aquatic animals have boat shaped bodies?
(i) The streamlined body shape (boat shape) allows the fish to move easily in water.
What is a streamlined body how it is helpful for a body to have such a shape?
Streamlined body means body which can offer minimum resistance to air and water by its particular type of body shape. Streamlined body helps bird to fly easily in air by reducing resistance by air and in case of aquatic animals, streamlined body helps to swim easily through water by reducing resistance by water.
What is a streamline 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.
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 are streamlined and bluff bodies?
A streamlined body looks like a fish, or an airfoil at small angles of attack, whereas a bluff body looks like a brick, a cylinder, or an airfoil at large angles of attack. For streamlined bodies, frictional drag is the dominant source of air resistance. For a bluff body, the dominant source of drag is pressure drag.
Why do dolphins have 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').
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.
What is Astreamlined body How does it help in movement of animals that fly or swim in water?
Streamlined body lowers the friction drag between a fluid, air or water and an object moving trough that fluid. Drag is a force that slows down motion. Streamlining reduces the surface area of the moving object.
Why do fish have oval and streamlined bodies with pointed snouts?
The bodies of fish are the streamlined bodies because they have to move in fluids. Fluids exerts a force opposite to the direction of motion when an object (Fish) is moving in a fluid. This frictional force is known as drag. In order to decrease this drag the objects are given a special shape or streamlined shape.
What is streamlined shape explain and give two examples?
Answer: A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Example: Aquatic animals like fish, crocodile and sharks and the vehicles like cars, flights, ships ect. Streamlined shapes help reduce the amount of air drag when an object is moving.
