Overview
The Coral Hind (Cephalopholis miniata), also celebrated as the Coral Grouper or Jewel Bass, is an incomparably gorgeous, jewel-toned reef predator native to the sun-drenched coral reefs of the tropical Indo-Pacific. Flamboyantly dressed in brilliant, glowing orange-scarlet or crimson skin studded with hundreds of luminous, sky-blue circular spots, it is one of the most eye-catching denizens of tropical coral drop-offs.
Biology and Physical Characteristics
Cephalopholis miniata has a robust, oblong, laterally compressed body with a large head, strong protruding lower jaw, and sharp, backward-pointing teeth designed to grip slippery reef fish. Its coloration is breathtaking: a fiery crimson-orange to deep ruby-red base covered uniformly across the body, fins, and head with hundreds of small, bright cyan-blue polka dots circled by faint dark rings.
Behavior and Ecology
A dominant, highly territorial ambush predator of the reef crest, the Coral Hind claims expansive territories centered around prominent coral boulders and cave overhangs. An adult male oversees a harem of several females, vigorously chasing away competing groupers. It hunts primarily at dawn and dusk, launching lightning-fast lunges from coral caverns to seize passing damselfishes and anthias.
Conservation and Human Impact
Assessed as Least Concern by the IUCN, Cephalopholis miniata is common and widely distributed across intact coral reef systems. Valued both in artisanal reef fisheries for its fine white flesh and in the high-end marine aquarium trade, it is protected within major marine protected areas like the Great Barrier Reef Marine Park.
Interesting Factoid
Despite its blazing neon-red coloration to human divers, red light wavelengths are completely absorbed in the first few meters of ocean water; at reef depths of 30 feet, the Coral Hind appears totally black, making it completely invisible to passing prey.
