Crangon crangon
''Crangon crangon'' is a commercially important species of caridean shrimp fished mainly in the southern North Sea, although also found in the Irish Sea, Baltic Sea, Mediterranean Sea and Black Sea, as well as off much of Scandinavia and parts of Morocco's Atlantic coast. Its common names include brown shrimp, common shrimp, bay shrimp, and sand shrimp, while translation of its French name ''フランス語:crevette grise'' (or its Dutch equivalent ') sometimes leads to the English version grey shrimp.
==Description==
Adults are typically long, although individuals up to have been recorded.〔(【引用サイトリンク】title=''Crangon crangon'' )〕 The animals have cryptic colouration, being a sandy brown colour, which can be changed to match the environment.〔 They live in shallow water, which can also be slightly brackish, and feed nocturnally.〔 During the day, they remain buried in the sand to escape predatory birds and fish, with only their antennae protruding.
''Crangon'' is classified in the family Crangonidae, and shares the family's characteristic sub-chelate first pereiopods (where the movable finger closes onto a short projection, rather than a similarly sized fixed finger) and short rostrum.
