Humans are not the only ones with something unique to say. I just got back from the Bahamas, where I made a friend named Sasha, a bottlenose dolphin rescued from an aquarium damaged by Hurricane Katrina.
Sasha’s trainer Gary cued her several times to make her signature whistle. It turns out that dolphins can make a whistle that is uniquely its own. Calves develop their distinctive signature whistles over a four to six month period after birth. A recent study suggests that each dolphin call itself by name and recognises other’s names, too.
Dolphins like Sasha don’t just whistle, they click and squeak through their blow hole. Sound like anyone you know?
