The genetic study also revealed a comparatively low level of genetic diversity when compared to other humpback populations, as well as the signatures of both distant and recent genetic bottlenecks, events caused by population declines. The Arabian Sea humpback whales occur in the northern hemisphere and therefore exhibit similar breeding cycles to the other northern hemisphere populations.

The humpback whale population in the Arabian Sea (northern Indian Ocean) is the smallest and most endangered humpback whale population in the world. However, the genetics of Arabian Sea humpback whales indicates that they are an isolated remnant population from the southern hemisphere that occurred at least 70,000 years ago. The habitats of whales, dolphins and porpoises often overlap with human activities that can have harmful impacts on individual cetaceans and populations as a whole.

These populations are distinct. The separation is likely reinforced by breeding cycles that are asynchronous; humpback whales in the Arabian Sea breed on a Northern Hemisphere schedule, whereas the closest whale populations in the Western Indian Ocean (below the equator) breed during a different season. "The epic seasonal migrations of humpbacks elsewhere are well known, so this small, non-migratory population presents a wonderful and intriguing enigma," said WCS researcher and study co-author Tim Collins.
