Do slime mold have a language? Slime mold can learn and adapt to environments, so it is intelligent and can do rudimentary reasoning, but I doubt it communicates that information to other slime molds.
It is a very different kind of life form though so many things that applies to other complex being doesn't apply to them. Being a large single cell means that they learn by changing its proteins and other internals, very hard for us humans to reason about and understand since it is so alien compared to just having nerve cells with physical connections.
