The bright orange fan can may very well exceed a diameter of 1 meter. The fan is usually spread out transverse to the dominating current direction. This way it can maximize the volume of water flowing through. It is often hosting Gorgon's heads which exploit the excellent current conditions provided by the sea fan.
This is a traditionally viewed as a deep sea species, registered on depth ranges from 150 to 1600 meters. In the sheltered fjords they can be found already at 25 meters. Rivers provide a steady supply of cold, nutritious water. Stable low temperature and poor light condition during the summer, may be the major reasons for the shallow occurrences of this sea fan.
This sea fan is very common in the North Atlantic Ocean.
