It looks like a treelike formation with dense ramifications of dark red color, which fans form that can reach sizes of up to a meter in height. The terminal branches, claviform, are sometimes of yellow color. The skeleton is protein; the surface presents calcareous spicules that serve as shelter for polyps, retractable.
The colonies have the appearance of a real submerged wood, between the branches of which develops a remarkable biodiversity, it consists of every sort fish and invertebrates.
Distribution and habitat
It is a typical species of the Mediterranean Sea where populates rocky bottoms usually deep from 25-30 to over 100 meters, placing the emphasis on little crevices reached by the light. It is in fact a kind sciaphilous, that lover of twilight.
In the past colonies of red gorgonian we were very numerous, today we are witnessing a decline them throughout the Mediterranean, especially in surface water as a result of warming waters. Other factors that threaten its survival are indiscriminate harvesting by divers, and the damage inflicted by trawling. It is a species very fragile and very slow growth. By virtue of these characteristics is considered a biological indicator of the marine ecosystem balance.
