Blue-And-Yellow Grouper

Epinephelus flavocaeruleus

The Blue-and-yellow Grouper is a marine ray-finned fish associated with reefs in the Indian Ocean. This species is known for its distinctive coloration, with juveniles displaying a combination of sky blue and yellow hues. As they mature, their coloration shifts to a darker bluish violet or greyish blue, with yellow fins that tend to fade in larger adults. These groupers have a deep and compressed body, with a standard length that is 2.3 to 2.7 times their body depth. They can grow up to 90 cm, though the average size is around 45 cm. This grouper is found throughout the tropical waters of the Indian Ocean, ranging from the eastern coast of Africa to the northwest tip of Sumatra. It inhabits coral and rocky reefs, with juveniles preferring shallower areas and adults residing in deeper waters, up to 150 meters. The species is solitary and territorial, often defending its area from intruders. The Blue-and-yellow Grouper is a predatory fish, feeding on a variety of marine life including fish, crabs, shrimps, spiny lobsters, squids, and small octopuses. It is considered of 'Least Concern' by the IUCN, and while it is harmless to humans, it is commercially fished in some regions.
