Mote Aquarium's resident dolphins, Moonshine and Harley, help educate visitors about dolphins and other cetaceans found in the world's oceans. Moonshine is a pantropical spotted dolphin and Harley is a long-snouted spinner dolphin. Both are commonly found in deep tropical waters and are not animals that you would likely see if you went for a walk along a Gulf Coast beach.

Both dolphins were brought to Mote's Dolphin and Whale Hospital for rehabilitation after they stranded at young ages. After months of rehabilitation, the federal authorities that regulate the protection of wild marine mammals, the National Marine Fisheries Service, decided that the dolphins could not be returned to the wild. Those officials also decided that because the animals were both members of genus Stenella, were extremely social species and could be found together in the wild, they should be housed together for long-term care.
