Recorded distribution in Britain and Ireland

Recorded only in the middle and upper reaches of the Tamar Estuary, and the Dart Estuary, Devon. A similar brackish water community was recorded in the Bann Estuary, Northern Ireland.

Habitat preferences

Temperature range preferences - Data deficient

Water clarity preferences - Low clarity / High turbidity
Poor clarity / Extreme turbidity

Limiting Nutrients - Data deficient

Other preferences - Low / Reduced salinity

Additional information

In the Tamar estuary, Devon, available hard substrata consisted of small areas of bedrock, shells, underwater tree remains (stump and branches), and rubbish (e.g. tyres). The area was characterized by a relatively impoverished community of estuarine invertebrates, with low to reduced salinity between 30 to 5 psu and high turbidity with macroalgae restricted to very shallow water (Hiscock & Moore, 1986; Moore et al., 1998).
