Makes you imagine a world with high solar power density and maybe lower gravity or something where larger land animals might be realistically supplemented by solar energy as well.

Closer to the sun (high solar power density) and smaller (lower gravity)... I think we actually have one of those nearby?

Some infinite water supply would be probably helpful there.

Infinite indeed, need to keep it topped off as it all boils away.

		Now I think of a scifi setting, where rich people use massive ressources to feed their artificial gardens on Merkur with water from comets, so the genetically engineered solar powered green butterflies in their garden can keep flying. (But there might be more expensive adjustments needed, like rotation speed)

I suppose also 'is capable of supporting life' might be an important factor when considering hypothetical life forms.
