A fascinating story from CBC Radio — based on a new study in the academic journal Science Advances, dolphins can recognize the sound of a whistle or the taste of urine — yes, taste — to spot their friends.
What started as a study of how dolphins use their signature whistles has uncovered another way the cetaceans communicate: their urine.
“It’s like your dog sniffing a fire hydrant,” study co-author Jason Bruck told As It Happens guest host Robyn Bresnahan.
