To reduce friction and fuel consumption not to mention making it pleasing to the eye.
because of the shape
It's mainly to reduce fuel consumption. A streamlined shape needs less energy to push it forward against standard air pressure - than one that isn't streamlined.
A car can be streamlined by adding inserts to the sides or top to redirect air, or the shape can be changed to become more aerodynamic, or to redirect the air around to avoid being slowed down by air.
Their shape and aerodynamic efficiency makes them streamlined.

Their shape. Peace out. :)
Yes, they do.
because its round
It is to swim faster when it is catching their prey and running away from its predator. Its streamlined body shape helps it to 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
