What is steamlined body how is it useful to fish?

A streamlined body refers to a shape that reduces drag and resistance as an organism moves through water. In fish, this body shape is typically elongated and tapered, allowing them to swim efficiently and quickly. The streamlined design minimizes turbulence, enabling fish to conserve energy while navigating through their aquatic environment, which is essential for catching prey and avoiding predators. Overall, this adaptation enhances their survival and reproductive success in the water.
