Hector's and Maui's dolphins are classified in the same genus and species (the first two parts of a scientific name). Scientists have decided that the genetics and skeleton of Mauiâs dolphins are sufficiently different from those of Hectorâs dolphins to warrant placing the animals in different subspecies.
There is also a sub-species of the Hector's dolphin, called the Maui dolphin, which is found in the North Island. What do they look like? The Hectorâs dolphin is distinguishable from other dolphins by their rounded black dorsal fin which is shaped like a Mickey Mouse ear. Their bodies are a distinctive grey colour, with white and black markings.
In 2010, DNA fingerprinting showed that there were two South Island Hector's dolphins swimming with the Maui's dolphins. In 2011 one of those Hector's dolphins was sampled again in a similar area. This is the first record of this occurring. Although there is no record to show that female Hector's dolphins have interbred with Maui's dolphins, it is possible that they can, which might enhance their genetic diversity.
