This little sea animal is called “Costasiella kuroshimae” (known as “Leaf Sheep”). It’s an aquatic slug that looks like a cow or a sheep and that eats so much algae that it can photosynthetize. When it eats an algae, it absorbs all the chloroplasts and turns into a process of kleptoplasty namely it digests partially the plasts and keeps some for it. This covered algae sheep can be found in Japan, Indonesia and Philippines.
