Before you fantasize how this could be used in humans in the future, producing that single thought cost more energy than leaf sheep produce via photosynthesis in their lifetime - feeding of it requires energy efficiency any warm-blooded animal just isn’t suited for.
Still cute though.
This is a god damn Pokemon.
Screw the Leaf Sheep. It’s all about the North American House Hippo.
they aren’t the only animal that does it: https://en.wikipedia.org/wiki/Kleptoplasty#Animals
Kinda but not quite:
Costasiella kuroshimae are capable of a physiological process called kleptoplasty, in which they retain the chloroplasts from the algae they feed on. Absorbing the chloroplasts from algae then enables them to indirectly perform photosynthesis.[6]

And I’m pretty sure there are also jellyfish that live in symbyosis with algae that they carry along with them which photosynthesize, creating sugars for the jellyfish.
homo sapiens is known to use photosynthesis through symbiotic relationships with various grasses to create sugars, lipids, and proteins for itself
Eh, that’s a few dozen steps removed. By that standard, every herbivore “uses” photosynthesis.
These guys (coral & lichen too) use photosynthesis much more directly, completely encapsulating the algea and supporting it internally. It’s much closer to mitochondria.
Reminds me of Lichen! https://en.m.wikipedia.org/wiki/Lichen
