9 Real-Life Creatures That Are Definitely Pokémon

5. Leaf Sheep

Costasiella kuroshimae, or the Leaf Sheep/Sea Sheep is actually an adorable little cross-eyed sea slug, or nudibranch.

It's definitely a plant type, as this little guy is one of the only animals on the planet that can actually photosynthesise through a process known as kleptoplasty. It eats mainly algae and retains the chloroplasts found in it for its own purposes, extruding them into the "leaves" on its back.

They're not as good as plants at photosynthesis, but they're good enough that they're able to survive on nothing but sunlight for months at a time, making it one of nature's only solar-powered animals.
