Where do we find streamlined shapes in nature?

Streamlined shapes can be found in various natural forms, primarily in organisms that require efficient movement through their environments. For example, fish have sleek, elongated bodies that minimize water resistance, while birds often possess streamlined bodies and wings to enhance flight efficiency. Additionally, many plants exhibit streamlined shapes, such as the tapered design of leaves, to reduce wind resistance and optimize sunlight capture. These adaptations illustrate how evolution shapes organisms for better survival and performance in their habitats.
