Real-world information
The ocean sunfish, mola mola, is a tropical fish related to the puffer fish. It's the largest known bony fish, at up to 3.3m long and 4.2m tall, and weighing over 2 metric tons. When resting they will lay down on their side just below the ocean's surface in the sun, which is where they get their name. This behavior is believed to warm them, as prolonged exposure to waters below 12 °C (54 °F) can disorientate or even kill them.

Despite being classified as a bony fish, they have a skeleton largely comprised of cartilage, due to the sizes they reach. Like some other toothless bony fish, it has pharyngeal teeth, or teeth in its throat. Traditionally believed to feed primarily on jellyfish, they are now known to be generalist predators, also eating fish larvae, squid, crustaceans, and even eelgrass. Ocean sunfish are often victims of skin parasites, and they will invite small fish and even birds to clean their skin.
