How long do cuttlefish live?

Typical life expectancy is about 1–2 years.

What is the cuttlebone for?

The internal cuttlebone is used to control buoyancy.

Are cuttlefish intelligent?

Studies indicate cuttlefish are among the most intelligent invertebrates and have a large brain-to-body size ratio.

Sepia is the brown pigment cuttlefish release when alarmed; the word also became the English name for that color.

How big can cuttlefish get?

Most range 15–25 cm, while the giant cuttlefish (Sepia apama) can reach about 50 cm mantle length and over 10.5 kg.

What animals prey on cuttlefish?

Predators include dolphins, larger fish (including sharks), seals, seabirds, and other cuttlefish.

Q: What do cuttlefish eat?

They eat small molluscs, crabs, shrimp, fish, octopuses, worms, and other cuttlefish.

Cuttlefish are marine cephalopod molluscs in the family Sepiidae. They possess a unique internal shell called the cuttlebone that aids buoyancy, large W-shaped pupils, eight arms, and two tentacles with denticulated suckers used to seize prey. Typical sizes range from about 15–25 cm (6–10 in), while the largest species (Sepia apama) can reach about 50 cm mantle length and over 10.5 kg. Diets include small molluscs, crabs, shrimp, fish, octopuses, worms, and other cuttlefish. Typical life expectancy is around 1–2 years. Cuttlefish are noted for high relative brain size and are considered among the most intelligent invertebrates. They also release a brown pigment (sepia) when alarmed.

Commonly cited pressures include Predation.

The strongest linked planning options currently surface around destinations such as Malta, Gozo, Komodo and countries such as Spain, Australia, Indonesia for divers building trips around cuttlefish.
