Crangon crangon

Crangon crangon is a species of caridean shrimp found across the northeastern Atlantic Ocean. Its range extends from the White Sea in the north of Russia to the coast of Morocco, including the Baltic Sea, and appears also throughout the Mediterranean and Black Seas. Commercially important, it is fished mainly in the southern North Sea. Common names include brown shrimp, common shrimp, bay shrimp, and sand shrimp, while translation of its French name (or its Dutch equivalent ) sometimes leads to the English version grey shrimp. Description Adults are typically long, although individuals up to have been recorded. 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 subchelate first pereiopods (where the movable finger closes onto a short projection, rather than a similarly sized fixed finger) and short rostrum.
