It's no surprise humans are most impressed by human-ish things, selfish as they are. But I bet a chimpanzee would be highly impressed with you if you could survive even a single day in the jungle.

Do you think most animals just... never communicate? Why does it have to be something dumbed down enough that humans can interpret it? I bet a dog would be impressed with you if you could emit a scent that can be reasonably interpreted as some form of simple communication.

Not really. They're squishy and weak and quite fragile. Tardigrades are the only exceptional lifeform in this galactic neighborhood.
