A creature that looks like a green leaf from a distance is called Elysia chlorotica, which can obtain chloroplasts from swallowed algae. These chloroplasts are stored in its visceral cells, making its body appear unique green.

Once the number of chloroplasts in an adult reaches saturation, it can survive without food for as long as 10 month, and it depends entirely on photosynthesis. Photosynthetic ability has evolved in some animals of gymbranchia, and many subspecies have reached a * * * relationship with some * * algae. These animals usually get algae from corals and anemones they eat and chloroplasts from them. Actually, there are many ...
