- An internal shell, the cuttlebone, which is made of calcium carbonate
- A W-shaped pupil
- A complex brain and nervous system
- The ability to squirt ink as a defense mechanism
Environment

- Shallow coastal waters
- Coral reefs

They are typically found in temperate and tropical waters around the world.
