Dolphins are famously social and famously chatty, filling the ocean with clicks, whistles, and squeaks. But are they really talking to each other? The science is fascinating, and it turns out dolphins have one of the most sophisticated communication systems in the animal kingdom. Here is a look at how dolphins “talk,” including the remarkable discovery that each one may have its own name.
A Language of Whistles and Clicks
Dolphins make two main kinds of sound. Clicks are used for echolocation, their natural sonar for finding food and navigating. Whistles, on the other hand, are mostly social, used to stay in touch with the pod. Dolphins also communicate without sound, using body language like leaps, tail slaps, and touches to send messages to one another.
Do Dolphins Have Names?
One of the most amazing discoveries is that bottlenose dolphins appear to use “names.” Within its first months of life, each dolphin invents a unique signature whistle that identifies it, much like a name. Other dolphins learn these whistles, remember them, and even copy a friend’s whistle to call out to that specific individual. In studies, dolphins respond when they hear their own signature whistle played back.
How Dolphins Communicate
- Clicks are for echolocation: finding food and sensing surroundings.
- Whistles are social, used to stay in contact with the pod.
- Each dolphin has a unique signature whistle that works like a name.
- Body language like leaps, slaps, and touches sends messages too.
Why Pods Stay So Connected
All this communication helps dolphins live in tight-knit groups. Staying in constant vocal contact lets a pod coordinate hunting, warn each other of danger, care for calves, and keep their social bonds strong. It is part of why Oahu’s spinner dolphins travel, rest, and hunt together so closely, moving almost as one through the water.
Listen In on an Oahu Tour
Watching a pod of wild dolphins chatter and coordinate is even more magical when you know what is going on beneath the surface. On a responsible Oahu dolphin tour, some boats even use a hydrophone so you can hear the whistles and clicks for yourself.
