Risso’s Dolphins Documented In Kona!

Risso’s Dolphins Documented in Kona | April 17, 2024

Hawaiian Adventures Kona has seen some wild species offshore…a fin whale, mola molas, and even a humpback whale in July, but this was our first encounter with Risso’s dolphins! Risso’s dolphins are the fourth largest dolphin in Hawaiian waters, and are distinguishable by their unique coloration and large dorsal fin. Species like Hawaiian spinner dolphins and bottlenose are frequently seen, but Risso’s are a rare find as they prefer Kona’s deeper waters. 

Our Hawaiian Adventures tour was out on a year-round dolphin and whale watching trip when we had this unique encounter! In about 9000 ft of water we spotted the pod and cruised along with the group, snapping photos of the rare sighting! Captain Andrew Aggergaard, Naturalist Olivia Miller, and our guests onboard were thrilled to view and document this incredible species.  

An amazing variety of marine life can be found in Kona’s deep waters. From pilot whales and sperm whales to rough-toothed dolphins and Risso’s dolphins, you never know what you’ll find when you explore offshore. As one of the first companies to offer year-round dolphin and whale watching on the Big Island, we can’t wait to see what they’ll encounter on our next adventure!
