| Definition | Shallow sands with cobbles and pebbles, exposed to strong tidal streams, with conspicuous colonies of hydroids, particularly Sertularia cupressina and Hydrallmania falcata. These hydroids are tolerant to periodic submergence and scour by sand. Both diving and dredge surveys will easily record this biotope. Flustra foliacea and Alcyonidium diaphanum may also occur on the more stable cobbles and pebbles, whereas Lagis koreni is often a common component of the infaunal sand community. The less scoured biotope MCR.Flu.SerHyd occurs where there is less sand. Infaunal elements of the 'Venus' associations may occur in this biotope; indeed, this biotope may be at one extreme of the spectrum of such associations (E.I.S. Rees pers. comm. 1997). | |
