Sepia cuttlefish

Like other cuttlefishes, they have ink that they can use when scared, they move by jet propulsion and can change colour (not any colour, mostly they use very dark browns, light browns and whites. Sometimes they use a bit of orange behind their eyes, or grey in lines along their arms) to hide, or to send signals to other cuttlefish or to predators. They spend a lot of time on the bottom, and usually only swim when they are hungry (to catch prey), or when they meet another cuttlefish (they will fight or mate).
