Coral Hind

The coral hind (Cephalopholis miniata) is a mid-sized grouper in the family Epinephelidae, common on coral reefs throughout the tropical Indo-Pacific, from the Red Sea and East Africa to French Polynesia and southern Japan. Its bright orange-red body dotted with pale blue spots makes it one of the most recognizable small groupers on Indo-Pacific reefs. It occupies a middle position in the reef food web, preying on small fish and invertebrates while itself being prey to larger predators. The species is common and not currently considered threatened, and is frequently encountered by divers resting near coral outcrops and ledges.

Field marks for the coral hind:

• Base color: bright orange to reddish-orange over the entire body.
• Spotting: scattered pale blue to iridescent-blue spots, generally fewer and larger than the dense spotting seen in the leopard coral grouper.
• Body shape: robust, oval, and moderately compressed, smaller and stockier than Plectropomus groupers.
• Fins: rounded dorsal, pectoral, and caudal fins, all lightly spotted.
• Size: typically 25-40 cm, smaller than most true groupers. Its smaller size and sparser, larger blue spotting distinguish it from the more slender, densely spotted leopard coral grouper.

Coral hinds are widespread across the tropical Indo-Pacific, from the Red Sea and East Africa through the Indo-Australian Archipelago to French Polynesia, and north to southern Japan. They inhabit coral-rich reef flats, slopes, and lagoons, typically at depths of 2-150 meters, though most commonly seen between 3-30 meters near living coral. Adults are strongly associated with structurally complex reef habitat, favoring coral heads, overhangs, and crevices that provide shelter close to hunting grounds. Water temperatures across its tropical range generally stay between 24-29°C.

Coral hinds are solitary, territorial ambush predators that spend much of the day resting motionless near coral structure before darting out to seize small fish and crustaceans. They typically maintain a small home range centered on a preferred shelter site, such as a coral head or ledge. The species is a protogynous hermaphrodite, beginning life as female with some individuals later becoming male as they grow larger. Courtship and spawning occur in pairs, generally around dusk, with eggs released into open water. As an abundant mid-level predator, the coral hind plays a notable role in controlling small reef-fish and invertebrate populations across Indo-Pacific reefs.
