What is the difference between sharks and rays?
The obvious would be the shape: Sharks typically have a fusiform body (rounded and tapered at both ends). This shape reduces drag and requires a minimum amount of energy to swim. Rays are flattened, with their mouths located on the abdominal part of their bodies and gill openings. Eyes on sharks are situated on either side of their heads, while the eyes of rays are on top of their heads. Rays are famous for their barbed, venomous spine on a whip-like tail while most sharks have no spine. This is how they defend themselves from predators. Sharks main line of defense are their rows of razor sharp teeth, which are also good for ripping apart their prey. Reproductively, there are also differences; rays give birth to live young, while most sharks lay eggs. There are always exceptions to every rule but those listed above show common similarities and differences between sharks and their cousins, the stingrays.
