Common name: Cuttlefish

The order Sepiida encompasses the marine mollusks commonly known as cuttlefish. Members of this group are known for their unique internal shell, the cuttlebone, and their advanced camouflage abilities. Cuttlefish possess a highly developed nervous system, allowing them to change color and texture to blend into their surroundings, making them fascinating to observe in a reef aquarium. They are also intelligent and can be trained to recognize shapes and patterns. Cuttlefish require a specialized diet of live or frozen foods such as shrimp and fish, and they need a spacious tank with plenty of hiding places.
