Which fishes are said to have a streamlined body?
Class of fishes is known as Pisces. Fishes are said to have a streamlined body because their body is narrow at both the ends .
Which type of shape do most of the fish have that help them in swimming?
Q. Fishes have a streamlined body shape that helps them to move inside water.
Why do fish and birds have streamlined bodies?
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 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 is an aquatic adaptation streamlined body?
Explanation: Streamlined body of aquatic animal helps in their movement within the water body as it reduce water resistance when they swim . It is a type of structural adaptation.
What does it mean when something is streamlined?
Definition of streamlined
1a : contoured to reduce resistance to motion through a fluid (such as air) b : stripped of nonessentials : compact. c : effectively integrated : organized.
What would happen if a fish shape is not streamlined?
Gills are unable to absorb atmospheric oxygen, due to which the fish will die when removed out of water .
What is streamlined shape how does it help in animal that swim in water?
A streamlined body is a shape of the body which tapers at the ends thicker in the middle. Such a body shape reduces the friction drag between the medium (i.e., air or water) and the animals (e.g., bird or fish). Thus, it minimises the resistance of air or water and helps the animals to fly or swim easily .
What features of fish help it to swim?
- Fish have a streamlined body shape, flexible backbone, fins and strong muscles which help them to swim in water.
- Their body shape is such that water flows easily around it allowing the fish to smoothly move in water.
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 that 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.
Do birds and fishes have a streamlined body?
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.
Why are the bodies of fishes streamlined Brainly?
Answer: The body of bony fish is streamlined because. ... it increases the speed of fish in water . 2. the streamlined shape of the body acts as aerodynamic regulator i.e, more the streamlined shape,more easier for the fish to swim.
What is the most hydrodynamic animal?
No. 1 on the list is the super-speedy sailfish . While it doesn’t necessarily swim at heightened speed all the time, its fastest leap has been recorded at 68 mph (109 kph). These amazing creatures live in both warm and temperate waters and grow very quickly.
Which animal has a streamlined body?
Many animals that move through water are streamlined, including different kinds of fish, whales, stingrays, eels , and more. Marine animals are not the only ones with streamlined bodies, weasels are one example of a land dwelling animal with a streamlined body. Most types of birds will also have streamlined bodies.
Do amphibians have streamlined bodies?
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.
Does aquatic animals have streamlined body?
A streamlined body is a shape of body that reduces resistance when moving. Some animals, such as shark and dolphins, are streamlined so that they have less resistance when swimming in water.
How does streamlined body helps fish to swim in water?
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.
How do fish utilize streamlining?
Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side . This action propels the fish much like sculling (rowing a boat with an oar) propels a boat. The caudal fin or tail is not the only fin a fish uses to swim.
What is a streamlined look?
designed or arranged in a way that makes movement easier through air or water : a streamlined shape/appearance.
How do you streamline a process?
- Identify the goal or end result.
- Break down the process into discrete steps or tasks.
- Analyze the process steps, perform value chain analysis, evaluate handoffs, and identify bottlenecks.
