To assess the sensitivity of the biotope, the sensitivity of component species is reviewed. Those species that are considered to be particularly indicative of the sensitivity of the biotope, and for which research has been undertaken in detail are shown below (see selection criteria). The biology of other component species of the biotope is also taken into account wherever information is known to the researcher.
|Community Importance||Species name||Common Name|
|Important characterizing||Virgularia mirabilis||A sea pen|
|Important characterizing||Amphiura filiformis||A brittlestar|
|Important other||Pecten maximus||Great scallop|
Virgularia mirabilis is the main important characterizing species, giving the name to the biotope. Amphiura filiformis is representative of brittlestars which are also important characterizing species associated with this biotope. Virgularia mirabilis and Amphiura filiformis are both burrowing species and can be important structurally. Pecten maximus is an important commercial species associated with this biotope.
