Definition

Noun: 1. A type of coral: Gorgonian coral refers to any coral belonging to the order Gorgonacea (or Alcyonacea), characterized by a flexible, branching internal skeleton. This skeleton can be made of a horny protein (gorgonin) or calcareous (calcium carbonate) material. They are often called sea fans or sea whips.

Advanced Usage
