Researchers first film humpback whales mating - both animals are male. One of the two sea giants appeared sick, had unusual brownish skin discoloration and whale lice.
The researchers suspect that he wanted to escape mating with his conspecific. Homosexual activity is not uncommon in the underwater world. Similar observations have already been made in walruses, dolphin species and seals. Unusual crossbreeding in the animal kingdom also occurs more frequently than expected - in the USA, a shark is said to have impregnated a stingray.
