Whale pods could be considered communities, and because of this I say that whale songs are language.

And from the perspective of other aquatic life? Communication is an absolute, transferring information from one to another. It’s built on dialog structuring ideas and thought through the use of auditory speech and symbolism. English uses inflections while mandarin is tonal, yet we can still successfully communicate once language is decrypted. We know dogs communicate, cats, birds etc but since we’re not the same species context based deduction isn’t possible without an accurate frame of reference, while we do know about whale speech and log their language the animals don’t. It would sound like reverberating scales of noise, closer to music.
