Ocean Sunfish

3D Ocean Sunfish, or 3D mola, develop their truncated, bullet-like shape because the back fin which the 3D ocean sunfish are born with simply never grows. Instead, it folds into itself as the enormous creature matures, creating a rounded rudder called a clavus. The 3D ocean sunfishare the heaviest of all the 3D bony fish, with large specimens reaching 14 feet vertically and 10 feet horizontally and weighing nearly 5,000 pounds. As a result, these 3D ocean sunfish are clumsy swimmers, waggling their large dorsal and anal fins to move and steering with their clavus.
