“Dolphins keep their mouths open and sample the urine of familiar individuals for longer than that of unfamiliar individuals,” researcher Jason Bruck of Stephen F. Austin State University in Texas told AFP.

“This is important because dolphins are the first vertebrates to demonstrate social recognition through taste alone,” added the lead author of the study, published in the journal Science Advances. According to the study, using the sense of taste as a detection method could be very advantageous in the open ocean, since urine plumes persist for a while after an animal swims away.
