You say it like it wouldn't be fascinating just by itself. About 70% of Earth's surface is covered by water and more than 90% of the ocean still remains unseen by human eyes. We don't even know what incredible creatures could be living deep in the ocean let alone on another planet!

Oh and by the way, even the fact that we can't have a "decent conversation" with other species doesn't mean they are not intelligent (whatever that means). Most people would considered dolphins stupid but it seems that they could be communicating with each other using some kind of sono-visual language and maintain quite complicated social structures.
