Whales

We have indeed known for a while that whales are intelligent creatures, with their own eerie and complex form of sound-based communication.

Since the 1970s, humans have been entranced by the songs of humpback whales, for example.

Sperm whales use a series of clicks, called codas, to communicate.

But another kind of whale communication, among the very social if less musical sperm whales, has more recently become a focus of research into exactly how whale communication, or language, might work.

In recent years, our technological ability to listen in on whales has grown in leaps and bounds.
