Psychedelic corals, From Heaven to Hell, Atlantic: The Wildest Ocean on Earth – BBC Two

Corals glow under ultraviolet light in what may be a unique form of sunscreen.

 Check out this clip from “From Heaven to Hell”,  the third episode of the BBC Two’s “Atlantic: The Wildest Ocean on Earth”. Scientists captured footage of a coral that essentially synthesizes its own sunscreen, in order to protect the symbiotic algae that lives in its tissue. Too much sun damages the delicate algae, so the coral produces a protein that absorbs ultraviolet light, and remits light of another color. The florescent reaction is visible at night under an ultraviolet light (the light of the sun drowns out the florescence), and the sight is otherworldly and beautiful.

If you are interested in filmography or photography, I recommend, as followup to the clip above, one titled “Making Atlantic: How to Shoot a Psychedelic Coral”. The entire series is available for purchase and download at the site as well.
