Did you know there’s an animal that uses photosynthesis? In this video, Quinten, a microhobbyist, shows us the microscopic world of flatworms, creatures that can blur the line between plant and animal in surprising ways. These flatworms host and protect algae inside their bodies, and the algae in turn produce oxygen and nutrients for the flatworm. This mutually beneficial relationship is called photosymbiosis!
