The Algae That Saved an Astronaut's Life

The video explores bioluminescent organisms, focusing on dinoflagellates. It recounts Jim Lovell's experience with bioluminescence during a flight and explains the ecological role of dinoflagellates. These organisms are crucial marine primary producers but can cause harmful red tides. Dinoflagellates have unique features like the dinokaryon nucleus and unusual swimming patterns. They exhibit diverse photosynthesis methods, including kleptochloroplasts. Their bioluminescence serves as a defense mechanism, attracting predators of their predators.
