Range & Status
A small shrimp-like species growing to about 13mm in length, found in brackish water in marshes and estuaries where it may be locally abundant. G.M. Spooner (M.B.A., 1957) describes it as ' found through Cornwall' but Bamber (2008) suggests that it is limited to six known sites, off Anglesey, North Wales and in south-west England, the estuaries of Fal, Fowey and Taw, off Plymouth and Teignmouth. Moves are being made to get it scheduled under the W&CA (Bamber, 2008).
