Fins of underwater animals are streamlined to make them glide through the water more easily, e.g. dolphins. Other animals include birds, whose beaks are at the front so they can too.
so they can swoop through the air
ELEPHANTS ARE NOT A STREAMLINED ANIMAL
Sharks, Tuna, Mackerels, and Marlins are all examples of Streamlined body shape fishes.
penguin is streamlined to swim in cold waters
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.
yes!
ELEPHANTS ARE NOT A STREAMLINED ANIMAL
Yes
yes
octopus and star fish
Fish, birds and snakes are a few
To be streamlined means to be designed or arranged to offer the least resistance to fluid flow. Aquatic animals are typically streamlined so they can move more effectively in water, which can enable escape from predators (or in the case of a predator, it's easier to catch your prey).
I think turtle and octopus

There is more resistance in water but fast fish are more streamlined than fast animals. A swordfish is faster than a cheetah.
A streamlined body takes less effort to force through the water.
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.
