Sandbanks which are slightly covered by sea water all the time
Large shallow inlets and bays
Brittlestars are predated on by a range of fauna that may visit the biotope. For example, Ophiothrix is preyed upon by crabs, dragonets and plaice although it does not appear to be a major food item for any of them (Warner, 1971). Ophiura are known to be a common prey for flatfish such as plaice (Downie, 1990 cited in Hughes, 1998) and Warner (1971) reported poor cod Trisopterus minutus shoaling over brittlestar beds in Torbay.
Can be protected as Reefs and also potentially within Sandbanks slightly covered by sea water at all times and Large shallow inlets and bays.
