We know so little.

Scientists have found that dolphins use unique whistles to call each other by name:

“We played signature whistles of animals in the group, we also played other whistles in their repertoire and then signature whistles of different populations – animals they had never seen in their lives,” explained Dr Janik.

The researchers found that individuals only responded to their own calls, by sounding their whistle back.

It is likely that dolphins have their own complex language, but we seem at a loss to understand it. We know so little about the world we live in.

I often contend that humans aren’t the smartest species on the planet, but we are the most arrogant.
