Spotted Eagle Rays have a striking appearance: a broad, diamond-shaped body (pectoral disc) with a dark dorsal side covered in white or pale spots or rings, and a contrasting white or pale underside. Their snouts are somewhat flattened and beak-like (sometimes called “duck-bill”), helping them to forage in the seafloor sediment. The tail is long and whip-like (often many times longer than the disc width) and may carry 2-6 venomous spines near its base for defense. These rays can grow quite large: disc widths of ~2–3 m are often reported, and total length including tail even more.
Spotted Eagle Rays are powerful, graceful swimmers. They often “fly” through the water with their wide pectoral fins, sometimes in small groups, sometimes alone. At feeding sites or in open water they may form loose schools. They are also known to leap out of the water occasionally, possibly as part of escape behavior or other social/physical reasons.
Diet
In terms of diet, they are benthic feeders: they use their flattened snout to probe into sand or mud for buried prey such as mollusks (clams, whelks, bivalves, gastropods), crustaceans (shrimp, crabs), worms, and occasionally small fish. They have strong, flat (crushing) dental plates which allow them to break open hard shells.
IUCN typically lists Aetobatus narinari (the spotted eagle ray) as Near Threatened, with populations decreasing in many parts of its range. Threats include bycatch in fisheries, habitat degradation (especially of coral reefs, bays, estuaries), and sometimes targeted capture for aquarium trade or local use.
