Coral reefs are easy to mistake for rock or plant life. But corals are animals—colonies of tiny polyps living in partnership with algae, building vast reef structures over generations. They are complicated creatures and they stretch our normal categories for living things. 

In this episode, we try to really get a grasp on this creature, with the help of coral biologists, writers, filmmakers and those who have been working to care for corals as they face many challenges. These experts see coral not just as an individual creature, but as a community—one built through symbiosis, cooperation, grief, and hope.

Along the way, the episode wrestles with climate change, extinction, restoration, and the spiritual weight of loving something vulnerable enough to disappear within a lifetime. Coral may look like rock from a distance. Up close, it becomes something much harder to categorize—and much harder to forget.
