Eight Arms With Lots of Ink

Octopuses are ocean animals known for their eight wiggly arms. They live in the water, but they are not fish. They are invertebrates, which means they don’t have backbones. In fact, they don’t have bones at all! That’s why they are able to squeeze their squishy bodies into very small spaces to hide. An octopus’s arms are usually covered in suction cups. The octopus can taste what it touches with these suction cups.

Octopuses eat small animals living in the oceans. Some of the things octopuses eat are crabs, lobsters, shrimp, clams, fish, and worms. Some larger kinds of octopuses can attack larger animals such as sharks.

When an octopus is threatened by a predator such as a whale, seal or large fish, it squirts out a cloud of black ink. The ink makes the water cloudy, and partially hides the octopus. The ink can also make it harder for predators to smell the octopus. This gives the octopus time to swim away. And they’re fast swimmers! To get away quickly, the octopus blasts water through the muscular tube on its body. This tube is called a siphon. Even if the octopus is unlucky and loses an arm, it can regrow it.

Marmo’s Tip: Don’t let dirty water drain into the ocean where my octopus buddies live. Keep it clean for all the ocean creatures!
