EUNIS habitat type code   A4.11 Level   4
Edition   EUNIS Habitat Classification 2012 - a revision of the habitat classification descriptions.

Description ( English )

This habitat type occurs in wave-exposed, tide-swept narrows and straits on circalittoral bedrock and boulders. The biotopes within this complex are characterised by a high abundance of the robust hydroid [Tubularia indivisa]. The barnacle [Balanus crenatus] is characteristic of A4.111, the cushion sponges [Halichondria panicea] and [Myxilla incrustans] are characteristic of A4.1121 and [Alcyonium digitatum] is characteristic of A4.1122. The anemones [Sagartia elegans], [Actinothoe sphyrodeta], [Urticina felina], [Corynactis viridis] and [Metridium senile] are all found within this complex. Other species present in this high-energy complex are the sponges [Esperiopsis fucorum] and [Pachymatisma johnstonia], the bryozoans [Alcyonidium diaphanum] and [Flustra foliacea], [Cancer pagurus], [Sertularia argentea] and [Asterias rubens].
