Marine biologists working off Hawaii have confirmed the sighting of a hybrid of two dolphin species.
The discovery was made after the group working off the island of Kauai spotted a mixed group with unusual features.
As outlined in a newly published research paper, a skin sample was collected and DNA testing confirmed their suspicions.
The genetic test showed the hybrid had the mitochondrial haplotype of a melon-headed whale, which means the mother was a melon-headed whale, and the father was a rough-toothed dolphin.
