Humpback sex photographed for first time – and both whales were male

Scientists confirm sighting of two same-sex marine giants copulating in amorous encounter off Hawaii coast

Humpback whales have been observed having sex for the first time, with this landmark moment having an interesting twist - the two whales were male.

Despite decades of research on humpback whales, sightings of the male's penis have been rare. Copulation by the species had not been documented by people - until now, when two photographers captured images of a sexual encounter between two whales off the coast of Hawaii.
