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.
A streamlined body takes less effort to force through the water.
The body of ships and boats are streamlined coz that they can experince minimum amount of Friction while moving through water
Its an adaptation created over time in order to help them maneuver through their environment. Evolution to be frank.

To help them swim with less fluid resistence, thus with less energy loss, which is one important driving factor in evolution. Streamlined bodies usually cause less turbulance and so are more "aerodynamic" in water or in any other fluid, such as air.
penguins streamlined body shape allows them to move quickly through water.
The shape of many objects moving through air or water is designed in such a way(with pointed ends) that friction can be reduced between the objects and water or air(fluid).The shape of the body is called streamlined body. Most fish are cold-blooded animals that have a streamlined body that is adapted for efficient movement in water. There are exceptions to both of these rules though.
To run fast through thick vegetation.
Yes it does it has a streamlined body
becaus it has a long, thin streamlined body to cut through the water. It also has lots of fins to push through the water like oars. by MACKENZIE SCOTT
it helps in reducing resistance in water
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.
