Longman’s beaked whales in Hawai‘i

We’ve only had a single sighting with Longman’s beaked whales (Indopacetus pacificus) – a group of ~35 individuals offshore of Kona in August 2007. In spite of this, there have been numerous likely reports of large groups of Longman’s beaked whales off the island of Hawai‘i and in offshore waters around the Northwestern Hawaiian Islands, along with a single stranding in March 2010. While this species remains elusive for the moment, we hope to encounter them again in the future!
