I've cracked some of dolphinese.
it's in sounds that don't come in a language but a sequence that portrays a message. a simple message but a powerful message none the less. e.g. squeaky whistle= I'm afraid, then the other dolphins escape from a shark or other danger. an observation made by scientists.

it's the same for monkeys. they make a different howl for a different predator, then it affects the monkey clan in a different way e.g. big cat, the monkeys go up, eagle the monkeys climb down and snake, the monkeys climb to a different tree.

bees have the most efficient form of communication because they just do a 1/2 second buzz/dance and it's told half the colony where there's nectar to be had.

ants don't make a noise but use pheremones, chemical signals that lead the other ants to do a task, e.g. 1 pheremone makes ants follow and another summons an ant army. . My lead into the world of creatures.
