Dolphins are wild man. I remember reading about some like post grad student in some government study living with a dolphin in a flooded house.
It would give her gifts and try to show off for her. And when she obviously brushed off his advances he got really sexually aggressive with her and biting her and she ended up letting him hump her leg or something.
He was sent to an aquarium and ended up drowning and the official report was it died of self asphyxiation due to a broken heart.
They also gave this dolphin LSD apparently, which I'm sure did not contribute to its death at all. Tragic 😔
