Deciphering the composite morphological diversity of Lophelia pertusa, a cosmopolitan deep‐water ecosystem engineer

Abstract Cold‐water coral reefs constitute important biodiversity hotspots in aphotic waters around the world. The complex, highly variable morphology of the reef habitat‐forming species has important implications for the communities they harbor and for the physical processes occurring therein. Loph...
