Coral 'Twilight Zone' Reveals New Type of Photosynthesis

Now, researchers have discovered that the corals that inhabit this "twilight zone" have a never-before-seen adaptation that enables them to eke out enough light energy to survive. The photosynthetic algae that live on and power these corals have unusual cellular "machinery" that enables them to conduct photosynthesis more efficiently than species that live at shallower depths, the researchers reported Oct. 17 in the journal Frontiers in Marine Science. "It's unlike anything we've seen on land, o
