Preferred label [Sertularia cupressina] and [Hydrallmania falcata] on tide-swept sublittoral sand with cobbles or pebbles
Definition Shallow sands with cobbles and pebbles, exposed to strong tidal streams, with conspicuous colonies of hydroids, particularly [Hydrallmania falcata] and to a lesser extent [Sertularia cupressina] and [S. argentea]. These hydroids are tolerant to periodic submergence and scour by sand. Both diving and dredge surveys will easily record this biotope. [Flustra foliacea, Balanus crenatus] and [Alcyonidium diaphanum] may also occur on the more stable cobbles and pebbles, with [Urticina felina] and occasional [Lanice conchilega] present in the sand. Infaunal components of the other biotopes in the SSA or SCS complex may occur in this biotope as may elements of the 'Venus' associations; indeed, this biotope may be at one extreme of the spectrum of such associations (E.I.S. Rees pers. comm. 1997) and this biotope may be best considered an epibiotic overlay.
