Dolphins
Dolphins depend on bromances: They need other guys to help them overpower the females they intend to bed. But the scientists Morell spoke to in Australia haven’t actually observed males and females mate, despite years at sea. What they do see, constantly and exclusively, is male-on-male action. It’s how the dolphins seal their precious alliances: “You do me, I do you, then we might both do her.” (Dolphins give new meaning to friends with benefits.)
Morell was surprised by the frequency of the behavior. “While we were out on the boat, researchers would call out what they were witnessing,” she says. “One of more common calls was, ‘Erection!’” Hey, they’re only human.
