The common cuttlefish is a widely distributed species in the eastern Atlantic (from the South of the North Sea and the Irish Sea to the West African coast). The cuttlefish, present on shallows, more or less all year long, can meet up to depths of about 150 m. It is an active predator feeding mainly on crustaceans and fish that it captures with its two large protractile tentacles. The prey is brought back to the crown of arms and then dilated by the mandibles, called “parrot’s beak.
