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 crevette grise (or its Dutch equivalent grijze garnaal) sometimes leads to the English version grey shrimp.
