Melon-Headed Whale Sightings

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. Two populations of melon-headed whales have been identified in Hawaiʻi: a smaller population resident to shallow waters off the northwest side of Hawaiʻi Island (Big Island) and a larger population that moves among islands and offshore.

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