Grooved cuttlefish

Gemeine Sepie

<em>Sepia officinalis</em>, the common cuttlefish, is a cephalopod mollusk belonging to the family Sepiidae. This remarkable marine invertebrate is found across the coastal waters of Europe, including Belgium, Denmark, Norway, and Sweden, where it typically inhabits shallow sandy or muddy sea floors as well as seagrass beds and rocky reefs. The common cuttlefish is celebrated for its exceptional ability to rapidly change skin color and texture, a trait used both for camouflage and communication. It possesses a unique internal shell called the cuttlebone, which functions as a buoyancy organ. <em>Sepia officinalis</em> is a carnivore, often preying upon small crustaceans, fish, and other invertebrates using its two elongated tentacles alongside eight shorter arms. The species typically employs jet propulsion for locomotion and can release ink to evade predators. Lifespan in the wild generally ranges from one to two years, with reproduction occurring in spring and summer in nearshore waters. The common cuttlefish plays an important ecological role as both predator and prey in coastal marine ecosystems.
