Oahu’s Other Dolphin
When people picture dolphins off Oahu, they usually think of the acrobatic spinner. But spinners are not the only dolphins in these waters. The bottlenose dolphin is the islands’ bigger, bolder cousin, and spotting one on a tour is always a treat. Here is how to recognize them and where you might see them around Oahu.
Bigger and Stockier
Bottlenose dolphins are noticeably larger than spinners. An adult can reach eight to twelve feet long, compared to the slender six- or seven-foot spinner. They have a thick, muscular grey body, a short stubby beak, and the famous rounded “smile” you see in movies and aquariums. They are also curious and confident, and often come close to boats to ride the bow wave.
Where You See Them
Unlike spinner dolphins, which gather in big groups close to shore to rest during the day, bottlenose dolphins around Oahu tend to travel in smaller groups and range a bit farther out. You might see them anywhere along the leeward and south shores, often mixed into a tour that is also watching for spinners, turtles, or winter whales. Because they are less predictable, a bottlenose sighting feels like a lucky bonus.
Spinner vs Bottlenose at a Glance
- Size: bottlenose are bigger and stockier; spinners are slim and smaller.
- Beak: bottlenose have a short stubby beak; spinners have a long thin one.
- Behavior: spinners leap and spin; bottlenose love to ride bow waves.
- Groups: spinners rest nearshore in big pods; bottlenose roam in smaller groups.
Smart and Social
Bottlenose dolphins are among the most intelligent animals in the ocean. They use clicks and whistles to talk, each has its own signature whistle that works like a name, and they hunt and play in coordinated groups. Watching a pod work together, surf a wake, or check out your boat is a reminder of just how clever these animals are.
Watch Them Respectfully
Like all wild dolphins in Hawaii, bottlenose dolphins are protected, and the best way to enjoy them is from a respectful distance while they decide whether to come say hello. Reputable crews never chase or crowd them. If a curious bottlenose chooses to ride your bow, you are in for an unforgettable moment.
