Yes. Like many semi-aquatic mammals, the platypus has a streamlined body. This enables the platypus to swim and dive faster.
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.
There is more resistance in water but fast fish are more streamlined than fast animals. A swordfish is faster than a cheetah.

Many animals have streamlined body shapes and hollow bones, for the simple reason they strive to go faster, either in a water environment or in the air (Aerodynamics). Birds have hollow bones and usually have streamlined bodies if they are the product of natural evolution, unlike many game birds today. In the water, many of the more aquatic mammals, such as Otters, are streamlined to go faster underwater. They do not, however, have hollow bones, their weight supported by the water, as is the case with many of the mammals. Seals and such do not have hollow bones, although they have a layer of blubber and smooth skin, and a mainly streamlined body.
Sharks, Tuna, Mackerels, and Marlins are all examples of Streamlined body shape fishes.
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.
an animal, car or boat are streamlined because most animals, cars or boats have round corners and they are low to the groung this means that they go faster because streamlining helps us go faster and the rounder a shape is the faster it will go
The breathing rate of aquatic animals is faster than that of terrestrial animals because the amount of dissolved oxygen in the water in much less than the amount outside, so they have to breathe more in order to get more oxygen
because there are less amount of dissolved oxygen in water so that aquatic animals breathe more faster in order to get more oxygen.
