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 just got to see a different species of kleptoplastic sea slugs in the wild last month, on a kayak tour of the mangroves around Key West. Our guide scooped some lettuce sea slugs up in a plastic container (and then returned them safely). They were bigger, about 3 inches long, with a wavy/frilly green border. It made my biologist heart very happy!

That was likely a sea slug from the Nudibranchia order (they resemble lettuce sea slugs sometimes) which are a bit different from Sacoglassa order slugs like the one in TFA in that they carry symbiotic algae colonies, rather than digesting them and keeping the chloroplasts like Sacoglassa.

This is one of those times evolution doesn't make sense to me. It's clear how a giraffe's neck evolves, the ones that could reach higher leaves in trees had an advantage. In examples like this, how does this evolve when there is no gradual change? An animal had to exist that had an offspring that somehow both absorbed the chloroplasts of the food it ate in a way that it could use (not just simple digestion), then have a place to store them, then have a mechanism to move the chloroplasts to the storage space, then have the mechanisms in their body to use the energy the stored chloroplasts create. How does that happen gradually when each step is totally useless without the others?

(please note I am not challenging the scientific truth of evolution, I simply do not understand how something like this happens)

They look kind of translucent to me, maybe the first of this kind of slug just had a digestive problem that didn't break down the chloroplasts, and the minimal energy through their bodies made those individuals more successful because they didn't need to eat as often as those who digested theirs. Yada yada other errors among the indegestible-chloroplast population showed further advantages when it's closer to the skin, they outcompeted their peers, etc.

Do you consider things that are inside a house to also be outside a house?

Is the coffee actually in the mug or only on top of it?

Life is amazing.

Stuff like this really makes you wonder what life might look like out in the universe.

Sounds like you might be interested in “The Zoologist’s Guide to the Galaxy”.

Evolution isn’t a matter of faith, you’re welcome to challenge it and try to poke holes in it.
