How do marine creatures like hammerhead sharks and rays use their unique head shapes to their advantage in the ocean?
Marine creatures like hammerhead sharks and rays use their unique head shapes to their advantage in several ways. The wide, flattened shape of the hammerhead shark's head, for example, allows it to have enhanced sensory abilities by providing more space for specialized organs called ampullae of Lorenzini, which can detect electrical fields and help the shark locate prey. The placement of its eyes on the ends of its wide head also gives the hammerhead shark a wider field of vision, allowing it to see more of its surroundings.
Similarly, rays have a flat, disc-shaped body and a long, whip-like tail. Their head is located at the front of their body, and their eyes and spiracles are located on top. This unique head shape allows rays to bury themselves in the sand on the ocean floor, with only their eyes and spiracles exposed. They can then lie in wait for prey to swim by, or use their fins to create currents that stir up small creatures in the sand for them to eat.
