🪸 Coral Polyp Cutaway: Zooxanthellae Expulsion, Oxidative-Stress Lag, Light and Heat Stress, Starvation and Recovery

A coral polyp cut open at 700 times life size: raise the water temperature, add bright light or nutrients, and watch the golden partner algae be expelled, the host reserve drain and the polyp bleach, starve or recover. Includes a lagged oxidative-stress model and exact closed-form checks.
