Cuttlefish are marine cephalopods belonging to the order Sepiida, known for their unique ability to change color and texture, which helps them camouflage in their environments. They are closely related to squids and octopuses and are characterized by their distinctive cuttlebone, a buoyant internal structure that aids in buoyancy control. Cuttlefish exhibit complex behaviors, including advanced communication methods through color changes and body patterns, showcasing their intelligence among invertebrates.
