I'm not an expert, by any means, on marine life but the dolphin seems happy. She seemed eager to take her *passenger* for his trip and just as eager to tell the trainer about it.
Because she understands that if she doesn't do it exactly that way, she doesn't eat. She knows she's supposed to act happy and friendly, go straight back to the trainer, etc.
why would they want to be there you dumb shit watch a look it up its so cruel they dont like it. dolpins are made to be free not kept in captivity. how would you like to be in a cage for your life.
Because that would put immense stress on the dolphin to keep itself and the Human afloat and you can see in the video that the dolphin is already having difficulty swimming. And it would hurt the dolphins back.
