Some fun facts about my favorite fish - Sunfish
1. Ocean Sunfish are huge. They're the heaviest
bony fish in the world, weighing on average over 2,000 pounds. They can grow over 10 feet long and more than 8 feet from fin to fin.
2. They have unusual skeletons. The ocean sunfish's spinal column contains fewer vertebrae and is shorter in relation to its body than that of other fish. It has a reduced skeleton that is mostly cartilaginous, and also lacks ribs.
3. They don't have tails. In most fish the tail is the main means of propulsion, but the ocean sunfish lacks a tail. They also don't have caudal fins. Instead, they have a structure called a clavus, formed by extensions of the dorsal and anal fin rays and used like a rudder. They "paddle" with their dorsal and anal fins, waggling them in the same direction at the same time to move forward.
4. Ocean sunfish have beaks. Their teeth are fused into a beak-like structure, and they have pharyngeal teeth located in their throats.
5. They have thick skins. Ocean sunfish don't have scales. Instead, they have a thick, rubbery skin that is covered in mucus. Their skin can be up to 3 inches thick in some areas.
6. Ocean sunfish eat mainly jellyfish. Ocean sunfish consume jellyfish, salps, squids, crustaceans, small fish, fish larvae, and eel grass. This diet is nutritionally poor, so they have to eat large amounts to maintain their great size.
