Morphological and trophic coupling distinguishes coral clades along a light gradient

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Light availability is critical to the growth and survival of most scleractinian corals due to their endosymbiotic relationship with photosynthetic dinoflagellates. Natural light gradients are expected to be associated with shifts in coral physiology, morphology, and trophic strategy.
