Stuff like this really makes you wonder what life might look like out in the universe.
Some things on Earth (especially in the ocean) you'd think were extraterrestrial... What a gift to still be able to find such amazing animals out there.

Or Hacker News for that matter. Never trust anything on the internet [1] on face value. Start by asking qui bono? Is this a reputable source, like a scientist[2]?. Be critical and sceptical. [1] https://en.wikipedia.org/wiki/On_the_Internet,_nobody_knows_... [2] https://youtu.be/NV0Z6vlIJig?t=216

I remember as a kid wondering if we could give humans chlorolaplasts.
Somewhat related https://what-if.xkcd.com/17/ The surface is too small and you only get like 4% of the energy you need (Assuming you like being naked under full sunlight all day long. The article is for cows, but I guess the number is similar for humans.) 4% of 2400 kcal is almost 100 kcal, that is the content of a small diet treat or 2 apples. These sea slugs can survive because they move very slowly. For a human, I…
Assuming a spherical cow and a spherical human, the calories needed would scale with the radius cubed, whereas the calories gained from sunlight would scale with the radius squared. So while I agree this wouldn't be very many calories, even if you sat under the sun all day, I think the 4% figure is probably quite pessimistic.

Is the coffee actually in the mug or only on top of it?
In Spanish I don't care.
* "El café está en la taza." [preferred]
* "El café está sobre la taza." [I'd never use this.]
* "El café está adentro de la taza."
I'd probably use "en(in?)" for a cup, "sobre(over?)" for a plate an "adentro de (inside?)" for a jar.

Don't trust anything you read on the internet, including your comment.

I believe that mitochondria and chloroplast both were originally independent single celled organisms. So kind of funny that, chloroplast is being "stolen" again by this sea slug.

Dietary need scales with volume, whereas incident sunlight would scale with surface area. Assuming a spherical cow and a spherical human, the calories needed would scale with the radius cubed, whereas the calories gained from sunlight would scale with the radius squared. So while I agree this wouldn't be very many calories, even if you sat under the sun all day, I think the 4% figure is probably quite pessimistic.

What would be extraordinarily interesting would be if we could find life on Earth with a fundamentally different biochemstry. Very different genetic code, even. This would be sign that Origin of Life is not the Great Filter. And we don't even have to go to another planet to conduct this search for "alien" life.
