Yet again, you fail to consider my previously mentioned other energy source.

If the limit to a biological aquatic creature is by how readily it achieve sustenance in its environment, then having the creature feed off of non-biological material would make sense in a way. There would be no real competition in the area, as the water would readily be the temperature(or as close as possible) of the geothermally warmed surrounding a chasm such as the Lava Lakes region. Second, the creature’s body, if it possessed multiple such thermal “generators” would be able to fairly evenly disperse power throughout the creature’s body in stronger concentrations. Finally, the thermal energy would take no other energy to process it, unlike normal creature’s which need entire bodily systems to break down biological matter and compost it into usable chemical energy.

Furthermore, in the case of Subnautica, the creature would have no way for such bacteriums as the kharaa to affect it.
