Desmophyllum dianthus has had several names since its initial discovery. Sometimes it is called the cockscomb coral for their elaborate septae – the fine blades that divide the coral tissue that are evident in this image. Clusters such as this may be clones, and the team on the Deepwater Canyons 2012 expedition took genetic materials to confirm this hypothesis. Stony corals like this one come in many shapes and sizes, from branching colonies that can form massive reefs, to tiny solitary or ‘cup’ corals that are only a few millimeters across.
