Flustra foliacea with hydroids, bryozoans and sponges on slightly tide-swept circalittoral mixed substrata
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Often dense Flustra foliacea with a variety of slightly scour/silt-tolerant species forming a dense turf on bedrock, boulders, cobbles and mixtures of sediment. This biotopes does not include the ascidians found in the silty biotope StoPaur although it can have similar suite of 'ubiquitous' species and the more scour-tolerant ascidian Polyclinum aurantium. Other species can include Alcyonidium diaphanum (see SNemAdia which has more hydroids and less Flustra), various robust hydroids such as Abietinaria abietina and Nemertesia antennina and sponges such as Dysidea fragilis, Polymastia boletiformis and Cliona celata. Has been recorded adjacent to exposed circalittoral rock communities with dense Corynactis viridis, although the data has not always been recorded separately. Securiflustra securifrons often occurs in this biotope.|
