Octopodes (Greek plural :)) and other cephalopods don't make noises,
but can change colour, pattern and texture of their skin, and use
this to communicate emotion and for camouflage. this could develop
into a visual language, they could also have a sign language based on
movement of their tentacles.
They already build shelters and cuttlefish (who are social) are known
to display one pattern one way and another the other,i.e. blank toward
a higher ranking male and courting display toward female on the other
side.
