A female bottlenose dolphin “BJ” performs her daily exercises while her trainer, Dera Look, supervises at the joint Marine Mammal Research Program on board Marine Corps Base Kaneohe Bay, Hawaii. Professionals and students from the University of Hawaii are studying dolphin hearing and echolocation, the use of sound waves to see.
