How have sting rays evolved?

Stingrays have evolved from ancestral cartilaginous fish, adapting to a benthic lifestyle in various aquatic environments, from shallow coastal waters to deeper ocean floors. Their flattened bodies and wing-like pectoral fins enable efficient movement and camouflage against predators. Additionally, their specialized electroreceptors, called ampullae of Lorenzini, allow them to detect electric fields produced by prey, enhancing their hunting capabilities. Over time, variations in size, shape, and feeding habits have emerged, allowing them to thrive in diverse ecosystems.
