Think about people you know, and how you could tell they were around even if you couldn't see them: perhaps their voice, or a favored perfume.
For bottlenose dolphins, it's the taste of urine and signature whistles that allow them to recognize their friends at a distance, according to a study published Wednesday in"Dolphins keep their mouths open and sample urine longer from familiar individuals than unfamiliar ones," first author Jason Bruck of the Stephen F. Austin State University in Texas wrote in an email to AFP.
This alerts dolphins to the recent presence of that individual even if it had not signaled its presence vocally. For the purposes of this study, the dolphins were trained to provide urine samples on demand in exchange for food.For the second part of the experiment, the team paired urine samples with recordings of signature whistles played via underwater speakers, corresponding to either the same dolphin that provided the urine sample, or a mismatched sample.
