Critically endangered right whales spotted in the Bahamas for first time

Hamilton added that it’s also unusual for two North Atlantic right whales to stick together unless they’re mother and calf, which Koala and Curlew are not. Researchers have been tracking Koala since her birth in 2009 and Curlew since hers in 2011; the pair have been seen swimming together for the last several months.

The reason for this will probably never be known except to those two whales, but... it's possible that some whales are gay. And that's okay.
