Question

Name three animals that have a streamlined body.

Answer 1

It is a shape of the body that reduces resistance when moving. This type of rover predators such as the salmon allow them to pursue prey. The lie-and-wait predator with a pointed snout, torpedo-shaped body, and large posterior fins is able to generate sudden thrust and acceleration.

Complete answer:
The shape of the body is said to be streamlined if the body tapers at both ends.
Examples: Fishes have streamlined bodies so that they have less resistance when swimming in water. 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. This same idea works with airplanes! When things are flat, like a bit of paper, they need more friction drag. Friction drag is like two things rubbing together. When airplanes fly they rub against air particles. This slows them down. To help reduce this drag we make planes smoothed out. This way air can move around airplanes quickly and are available together smoothly on the opposite side.

Additional information:
Aquatic organisms have a streamlined body shape. Streamline defines a shape that is wider at the center and narrows down towards the periphery. It provides minimum resistance while moving in air or water, providing ease of movement and increasing speed. The streamlined shape is not concerned with the storage of food or fats, neither is it associated with the reduction of water loss. Apart from this, it is also not associated with keeping the body warm. A streamlined body reduces friction and resistance to water while swimming.

Note: Fishes also have extensive sensory adaptations. The ability for chemore-ception is acute. Sounds and vibrations can also be sensed by the inner ear and lateral line system. This includes the power to sense remote objects by their hydro mechanical signals. Fishes even have a series of pit organs that allow sensing of weak electrical currents generated by prey. Numerous fishes have all around created eyes that encourage sight taking care of and sexual displays.
