@Bizmont They are also extremely friendly, and like to play with other dolphins, and even seals - to a point of dolphins actually jumping over to the orca part of the dolphinariums where it was possible. Such edenic idilia lasts only until orcas - inevitably - start to become a little peckish... Suffice to say, from that point onward they still will play with others, but their playmates will receive involuntary promotion to the status of game. And, a tad later - prey.
