What does it mean when dolphins rub fins?

They’re saying hi. Dolphins meeting up will caress each other’s pectoral (or side) fins. Researchers think it’s a greeting, like when we shake hands. Dolphins are known to rub their bodies up against each other, but also to engage in intricate rubbing behaviors using the pectoral fins. Dolphins will rub their fins into the fins of other dolphins, engaging in a behavior that looks a lot like holding hands. They will also rub the bodies of their friends, moving their fins rapidly over the face, flank or genital region, producing what is likely to be a pleasurable sensation. Sometimes dolphins will seek out rubs by positioning their bodies under the fin of their friend. Researchers have observed a behavior where dolphins will rest their fin on the back of their friend, holding it in place for hours at a time – likely a signal to other dolphins of their friendship.
