Quick answer
Cuttlefish feed on fish, crabs and shrimp, adjusting with season, age, and what is abundant in Coastal seas, sandy seabeds, and seagrass. That label is a preferred pattern, not every item an individual might sample.

Cuttlefish diet overview
Cuttlefish (Sepia officinalis) are best summarised as Carnivore (fish, crabs, shrimp). Anatomy and habitat (Coastal seas, sandy seabeds, and seagrass) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How cuttlefish find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Cuttlefish role in the food web
As predators or scavengers, cuttlefish move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild cuttlefish. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Range and habitat
Cuttlefish inhabit Coastal seas of the eastern Atlantic and the Mediterranean, over sandy and seagrass seabeds. Their preferred habitat includes coastal seas, sandy seabeds, and seagrass, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-term persistence across multipl
Physical characteristics and behaviour
Adult cuttlefish typically measure about 0.5 m in length and weigh roughly 2 kg (4 lb). They can sprint at up to 25 km/h (16 mph) in a jet burst when hunting or escaping predators. Cuttlefish are known for the color-changing master of camouflage — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.
