Happy hump day, everyone. A15-year study of humpback whales in the Southern Hemisphere is providing scientists with new insight into the slow giants' mating habits. Researchers analyzed DNA skin samples from more than 1,500 humpbacks in the South Atlantic and Indian Oceans. They found that the highest rate of "gene flow" occurred with whales breeding on either side of Africa, with one or two whales swimming between the Atlantic and Indian Oceans each year to mate. It was the first time a humpback had been recorded travelling between the two oceans. (Now that's what you call a long-distance relationship.) Another interesting conclusion from the study was that the small humpback population of less than 200 in the Indian Ocean, off the Arabian Peninsula, was distinct genetically and unlike other populations did not migrate and therefore was a "conservation priority."
