Summary

Description

A small shrimp-like species that grows up to about 13 mm in length. The head has lateral lobes that which are broadly truncated and the eyes are moderately large and kidney shaped. Antenna 1 has few hairs but antenna 2 in the male has many hairs, some long and curled. Male sub-claws (1st and 2nd appendages) and tail appendages also bear long curled hairs.

Recorded distribution in Britain and Ireland

Gammarus chevreuxi is may be locally abundant and has been recorded off Anglesey, North Wales, the River Taw estuary in north Devon, the estuaries of Falmouth, Fowey, and Plymouth, and at Teignmouth on the south coast.

Global distribution

Atlantic coast of Europe and north Africa

Habitat

Gammarus chevreuxi can be found in brackish waters, especially coastal marshes, saline lagoons and drainage ditches. It is often found on mud, sand and stones within estuaries.
