Friendly Playful Dolphin

"Did you know dolphins need to be in a pool with other dolphins? It's a law, because they're so social... like us... or me, anyway."

- Hazel, from Dolphin Tale

In most media, especially most fiction, dolphins are portrayed as playful creatures, who will easily befriend humans and like to play around in the water with them.

In real life, the extent of this varies. Dolphins can be trained to be like this, but one shouldn't expect this from wild dolphins, who are often hard to predict. Hence, experts recommend keeping your distance from them. This trope wouldn't have gotten its popularity if not for applying rather well to some dolphins, but the dolphins it's based on are the ones people see in aquariums and zoos; whom the label "trained" tends to apply to. They aren't going to be a representative sample of dolphins as a whole.

See also Heroic Dolphin, though dolphins can be portrayed as playful but not heroic, or heroic but not playful. Sometimes overlaps with Sapient Cetaceans, though cetaceans can be dolphins or whales, and also, dolphins can be portrayed as sapient but not playful, or playful but not sapient.

Classical Mythology

 * Boys riding dolphins were a common mottif in Roman and Greek art and literature and in latter art inspired by Classical themes. In some of the stories, the boys are in fact gods or demigods. Palaimon and Cupid are common choices. However, there were also stories of mortal boys that befriended dolphins and rode them. Pliny the Younger's letter include such a tale of a boy in the North African town of Hippo. According to the tale, while swimming, the boy was befriended by a dolphin that allowed him to ride it.

Real Life

 * Some scientific explanations of wild dolphin behaviour subvert this. For example, male dolphins typically leave the pod when they mature to pursue a solitary life or a life with other males. Sometimes, when males refuse to leave the pod, the females will push the males above the water line and expose them to the sun. Too much sun-exposure can be very uncomfortable for the dolphins, so this convinces the males to swim away. Sometimes, they will do the same thing to humans, possibly mistaking the humans for males that refuse to leave the pod. Of course, humans aren't threatened by prolonged exposure to the sun, so they think the dolphins are swimming with them, when really the dolphins are trying to drive them away.
 * Dolphins blow bubble rings.
