Risso's Dolphin Distribution

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. Risso's dolphins in Hawaiʻi are typically found in very deep waters far from shore.

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