The spectacular colours of coral reef fishes represent a ‘language’ that has been around for at least 50 million years – to which humans have lost the key.
Colour in fish is most probably a highly developed form of communication, some of which we can interpret, but much of which remains cryptic says Professor David Bellwood of the ARC Centre of Excellence for Coral Reef Studies and James Cook University.

Now I know something seem obvious, and I can cope with Sign Language… Semiphore,
Elephant communication is fantastic - if anyone has chance to read “SILENT THUNDER: In the Presence of Elephants” By Katy Payne. Did you know that elephants communicate with sounds that are below the range of human hearing? Similar to whales, they can speak over long distance with each other using infrasound.
But what other forms of communication are there out there.. Are we really that smart the human race? I think not.
