It’s unlikely an aquatic species can achieve technological breakthroughs needed to spread like humans can. It would be very difficult for them to build fires, smelt metal, and create the advances based off of those tools.
While they can be extremely smart and adaptable, it’s difficult to imagine how a species like that could develop machines.
Sure, there’s possible ways around it, like natural vents and geothermal power, but why would they utilize these resources without a benefit like cooking?
Some context for those of you who are confused as to why this picture is impressive.

The ISS rotates around the earth every 90 minutes, so before Don Pettit brought a custom built astrophotography rig up there this picture would have been impossible to take.
It’s weird that Eric Burger neglected to put this picture into perspective for people who aren’t 100% up to date on their space news.
