Obviously you're not wrong about fire being a major blocking point for sea creatures[1] - hard to make metals without fire. But possibly mermaids could "cook" their food via fermentation, e.g. putting food in a sealed swim bladder, then burying it in the sand. This could fulfill the same brain calorie requirements.
[1] Of course, maybe in Andromeda some sea-hackers are reading Hacker Sea-News and arguing land-based animals could never develop civilization because something-something.

- nicklecompte 3y agoYeah, too deep to keep watch over I think, unless they went for air in shifts. There's also the issue that if you're on land, gravity means you don't need an airtight container to cook/smelt/etc. But underwater it would be hard to prevent things from leaking to the sea. I think mermaids could do fish kebabs over a gas vent (though they'd lose a lot of food), but they couldn't use it as a kiln.
