Opah

The opah, also known as the moonfish, is a large, colorful, and unique species of lampriform fish. Distinguished by its rounded, disc-shaped body, vibrant coloration (typically red, orange, and white), and the remarkable ability to maintain a body temperature warmer than the surrounding water, a characteristic called endothermy, setting it apart from nearly all other fish species. This allows it to actively pursue prey in deeper, colder waters. The opah plays a significant role in the marine ecosystem, primarily feeding on small fish, krill, and squid. This solitary predator is sought after as a food source in certain regions, and due to its relative rarity, opah can fetch a high price in fish markets. It’s scientific classification is *Lampris guttatus*.
