Striped dolphins in Hawai‘i

Striped dolphins in Hawaii are typically found in very deep waters (our average sighting depth is 3,290 m) far from shore (our average distance from shore is 30.4 km). Striped dolphins in Hawaiian waters also typically avoid boats, sometimes from distances of several hundred meters, thus they are unlikely to be seen by most boaters in Hawaii.

Young calves ar frequently seen in the groups. Because we are not able to regularly get close to striped dolphins this is one species regularly encountered that we do not have a photo-identification catalog or any genetic samples.
