The *genus Lampris* refers to a group of large, colorful, and deeply-bodied oceanic fish. These fish, commonly called opah or moonfish, are known for their unique warm-bloodedness, a rarity among fish. Unlike most fish, they maintain a relatively constant body temperature, allowing them to thrive in a wider range of ocean environments. Think of them as the athletes of the sea, always ready for action! They are solitary creatures, often found in tropical and temperate waters. Their vibrant colors and impressive size make them fascinating subjects of study. They're like living rainbows in the deep blue.
