Spinner Dolphin Sightings

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. Although spinner dolphins are the most-frequently sighted odontocete seen in shallow nearshore waters, they are rarely seen offshore. Genetic evidence indicates three separate island-associated populations in the main Hawaiian Islands.

Dr. Joseph Mobley of the Marine Mammal Research Consultants (MMRC) led aerial surveys for cetaceans in Hawaiian waters from 1993-2003.
