I'm picturing a specie of intelligent aliens evolving on a familiar yet different Earth-like environment, these beings are capable of empathy and shares many similar psychological traits with us human. However, as they lack bones or faces they are incapable of typical human communication. They communicate with one another by merging with each other (they are slime like creature) such as the collective hive mind.
Can they develop language(s) and dialect(s)?
They are amorphous but not ethereal.
They can't see but hear. (vibration)
They merge their body and mind to communicate.
They will de-fusion/split apart to end commhnication.
They reproduce asexually through cell division.
They can extend part of their body to form as many as hundred of tentacles to grip object.
By touching with a single tentacle on each other they can only feel emotion but not thought.
P.S. As this is my first attempt on language comment below if there is any doubt pertaining to my alien species.
