The Opah, also known as the moonfish, is a large, colorful fish found in deep ocean waters. It has a round body and can grow up to 6 feet long and weigh over 200 pounds. The Opah is unique among fish because it can regulate its body temperature, allowing it to thrive in colder waters while hunting for prey like squid and small fish. This fish is easily recognizable due to its vibrant colors, which include shades of red, orange, and silver. The Opah is a popular target for commercial and recreational fishing, and its firm, flavorful meat is enjoyed in various cuisines. Its scientific name is Lampris guttatus.
