“Or look at dolphins. The bottle-nosed dolphin is catholic in its choice of sex partners. Males are frequently sighted copulating with turtles (they insert their penises into the soft tissues at the back of their victim’s shell), with sharks, and even with eels. Eels? Yes, when a dolphin’s penis is erect, it has a hook on the end—and many a male will use it to hook a writhing, struggling eel. So it should be no surprise that males also copulate with each other, inserting their penises into each other’s genital slits. The Amazon River dolphin, or boto, sometimes goes further, penetrating another dolphin’s blowhole. ”
