What The Cuttlefish Eats

  • Shrimp
  • Crabs
  • Fish
The Cuttlefish changes colours to hide itself in order to catch its prey easier. After it catches its prey with the sucker-pads on the end of its tentacles, it drags it to its sharp beak and eats it.

The Cuttlefish also has predators...

  • Fish
  • Sharks
  • Other Cuttlefish
When they feel threatened they eject ink to fool their predator and get away.


Males use their ability to change colours in many different ways other than hunting. They change colours to successfully attract a female. Some males make themselves look like females in order to trick a dominate male and steal their mate. A female can lay up to 200 small eggs but sadly dies soon after...
