i) Prominent difference between sharks and rays:
The most prominent difference between sharks and rays lies in their body shape. Sharks typically have a streamlined body with a fusiform shape, whereas rays have a dorsoventrally flattened body. This distinction is crucial in understanding their evolutionary adaptations and ecological roles. The flattened body of rays allows them to dwell on the ocean floor, while the streamlined body of sharks is adapted for open water hunting.
