A streamlined body takes less effort to force through the water.
Yes it does it has a streamlined body
ELEPHANTS ARE NOT A STREAMLINED ANIMAL
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.
Yes
Streamlined often means aerodynamic.
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.
A tuna and other fishes have a thunniform body plan which is streamlined to minimize drag within the water.
