Mantas and devil raysMobula

Mobula rays are characterised by their broad, flattened bodies, prominent cephalic lobes, and large, wing-like pectoral fins. The cephalic lobes, which project forward from the head, are rolled into a horn shape when cruising and unfurled into a funnel during feeding. Wingspans vary significantly within the group, ranging from approximately 1.8 m (6 ft) in smaller devil rays to up to 7 m (23 ft) in the giant oceanic manta. Dorsal surfaces are typically dark, often with pale markings on the shoulders, while their undersides are white with a unique pattern of spots used for individual identification.

These rays are open-water filter feeders, inhabiting both coastal waters and offshore pelagic environments. They feed on zooplankton, swimming open-mouthed through dense patches; mantas often perform a slow backward roll to remain within a plankton concentration. Mantas are frequently observed visiting reef cleaning stations on slopes and pinnacles, and may approach divers. Devil rays, however, generally remain further offshore, often forming large schools, and are less tolerant of close human presence.
