In a Poul Anderson book once, aliens communicated by scent. I wrote a short story about that- but it's very plausible. Also, don't octopuses (?) display colours and patterns that are signals?
They do! It’s unclear if that’s language (by the definition of “arbitrary symbolic communication”), however. Dogs barking is communication, for example, but it isn’t language.
Jury’s still out on whale and dolphin vocalizations, however.

I may have to repost my story "Lactose Intolerance" for you- it's amusing
You definitely should!
