Friction.
Streamlined .
the shape which is narrow in the beginning and broad in the middle is called a streamline shape. fishes have streamlined shape which makes their movement in water easier and helps to reduce water resistance.octopuses do not have a streamlined body but while moving it makes a streamlined body .boats ,fishes,airoeplanes etc have streamlineshape.
The most streamlined sea animal is often considered to be the dolphin. Its fusiform body shape reduces drag while swimming, allowing it to glide smoothly through water. This adaptation not only enhances its speed but also improves its efficiency in hunting and escaping predators. Other streamlined animals include sharks, which also exhibit similar hydrodynamic features.
The streamlined shape of the penguin makes it an excellent underwater swimmer, enabling it to cut easily through the water to catch fish- it's primary food source.
Yes, penguins have a streamlined body shape that helps them glide efficiently through the water while swimming. Their shape reduces water resistance, allowing them to move swiftly and catch fish underwater.
The body of ships and boats are streamlined coz that they can experince minimum amount of Friction while moving through water
the streamlined shape help to reduce air and water resistance like the shape of a plane and birds and fishes so as to reduce the over working and enable quick movement to it imposes less work not velocity
A streamlined body shape to reduce resistance in the water, limbs adapted for swimming or propelling through water, and possibly specialized features like fins, flippers, or webbed feet.
Streamlined animals have a shape that minimizes drag as they move through a fluid like air or water. This shape typically involves a sleek, aerodynamic design with smooth curves and reduced surface area, allowing the animal to move more efficiently through the fluid. Streamlined adaptations help animals reduce energy expenditure and move faster, making them more efficient predators or better at escaping predators.
wATER BEING STREAMLINED.
No. Some animals( example. Puffer fish) don't depend on speed so they don't have streamlined body shape. Other fish that depends on speed to catch fish or running away from predator have streamlined body shape so that they can swim faster.
The reason is because he most probably is using a streamlined body which allows him to cut through water.
