Concept: [Brissopsis lyrifera] and [Amphiura chiajei] in circalittoral mud in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A5.363
Preferred label [Brissopsis lyrifera] and [Amphiura chiajei] in circalittoral mud
Definition Mud in deep offshore, or shallower stable nearshore, waters can be characterised by the urchin [Brissopsis lyrifera] and the brittle star [Amphiura chiajei]. Where intense benthic dredge fishing activity occurs, populations of the indicator species, [Brissopsis lyrifera] may be depressed, although broken tests may still remain (E.I.S. Rees pers. comm. 1997; M. Costello pers. comm. 1997). Low numbers of the seapen [Virgularia mirabilis] may be found in many examples of this biotope. In addition, in certain areas of the UK such as the northern Irish Sea, this community may also contain [Nephrops norvegicus] and can consequently be the focus for fishing activity (Mackie, Oliver & Rees 1995). Infaunal species in this community are similar to those found in SpnMeg and include the polychaetes [Nephtys hystricis], [Pectinaria belgica], [Glycera] spp. and [Lagis koreni] and the bivalves [Myrtea spinifera] and [Nucula sulcata]. This community is the 'Boreal Offshore Mud Association' and '[Brissopsis - Chiajei]' communities described by other workers (Petersen 1918; Jones 1950).
