Dolphin dorsal fins become marked mainly through natural interactions free of any intentional nick/notch formation, meaning the markings are formed randomly. Even so, we do find “twins” among animals in the wild community.
Clearwater Marine Aquarium is open again with regular hours 10am-5pm daily and 6:30pm-9:30pm on Wed-Sun evenings for Aqua Lanterns! See more hurricane updates and donate to support our animal care and recovery efforts.
