Dorsal Fin Shape

Another distinguishing characteristic is the number of dorsal fins fish have

Fish fins help them balance, steer, and maneuver in the water. The dorsal fin is located on top of the body. Some fishes have multiple dorsal fins, while others only have one and some (like rays) have none at all. They can be triangular, rounded, long or short. How is the dorsal shaped?
