SS.SMu.OMu.ForThy recorded () and expected () distribution in Britain and Ireland (see below)
For a list of 2004 characterising species please see the JNCC website.
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.

|Important characterizing||Thyasira sp.||A bivalve|
The biotope is characterized by the presence of foraminifera and Thyasira spp. in the absence of either of these species the biotope would not necessarily be recognized. Polychaetes are usually abundant and their burrowing activity is important in controlling species diversity and abundance in the community.
In addition to species mentioned in the biotope description, polychaetes such as Exogone verugera, Nephtys spp., Aricidea catherinae and Minuspio cirrifera, and brittlestars, Amphiura sp. are also abundant in the biotope (Connor et al., 1997a) and information on these species has been used.
