Inter Tidal Zone Organisms

Blue-Ringed Octopus


My species, The Blue-Ringed Octopus, are mainly diurnal, which means we are out during the day. We often hide in caves or burrow under the sand at night. We can be found in Australia from Western Australia to eastern Victoria.

Information On This I.T.Z. Animal

We have a few different ways of moving around. Yes one of them is crawling. We sometimes travel along the ocean floor, shallow reefs, and even tide pools.
We take the easy way out and attack our food from behind, stick our beaks into our prey, and inject our toxic saliva and suck out their meat. We eat crabs, mollusks, shrimp, and sometimes other fish. Our main predator is the Moray Eel, but we also get eaten by wales and seals.
When aggravated the rings on our body turn blue. They cover the upper part of the mantle all the way down to our tentacles. We are covered with numerous papillae. We are about 5-7.8 in and we have a life span of 1-1.5 years.

One interesting fact about us, and all other octopuses, is that we have three hearts and blue blood.
