Rough-Toothed Dolphin Sightings

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. Rough-toothed dolphins are the most abundant odontocetes around the islands of Kauaʻi and Niʻihau although uncommon elsewhere. There is a small resident population of this species off Hawaiʻi (Big Island).

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