The ‘wings’ or pectoral fins of rays are made of a complex web of long, finger-like cartilage, which provides a great deal of control over movement. The wing resembles an aerofoil in cross-section, and gives the animal lift as it moves through the water. Their flat bodies make it possible to hide in sandy or muddy sea floors and evade predators.
