World’s Largest Cuttlefish: Australia (Video)

Australian giant cuttlefish, is the world’s largest cuttlefish species, growing to 50 cm in mantle length and over 10.5 kg or 23 lb in weight, they use special cells in their body to change their colour in an instant. They use these colours for protection when they wish to hide and the males use these different colours to attract a female, they can form beautiful coloured patterns of just about every colour of the rainbow.

They have a very short life span of 2 to 3 years. Because of their short life span, the cuttlefish reach maturity in around eight months. Their diet consists of fish, crabs and shrimp.

The cuttlefish has eight tentacles, two have sucker-pads, and before catching their prey they usually change colour to hide, then they use their long tentacles, once the prey is caught the cuttlefish then brings the prey to its mouth, the cuttlefish have a very strong sharp beak which they use to break the shells if they have caught such things as crabs. When not catching prey, their tentacles are retracted.

  1. Very cool – in the clip it almost looks like it’s hovering along the bottom on “fringe.”

  2. Those color changes are so dramatic!

  3. Linda Vernon says:

    Interesting! It’s just amazing how they turn color like that! How in the world do they do it? They looks so intelligent too. Amazing!🙂

      Hi Linda,
      They have a certain cell that produces these colours, this is how it is done so quickly, it is amazing to watch.
      Footnote:
      For some reason your comment went into spam, so if you don’t see your comment appearing on some blogs this is the reason. Obviously WP is having a few hickups, nothing unusual in that lately.

      • Linda Vernon says:

        I think octopi can do the same thing. And those are some smart cells!

        That’s weird that my comment went into spam! How weird. Is wordpress acting up weirdly for you. It’s doing all kinds of weird things for me. It’s typing over the same line — just weird stuff like that . . . hope it’s not my computer! YIkES!

        • magsx2 says:

          A lot of strange thing are happening, so I don’t think it’s your computer. There are a few others ending up in spam as well so you are not alone.
          As far as the typing goes this sounds a bit like a browser issue. Try clearing your browser cookies etc, go off the net and then click back on and see if that helps.

          • Linda Vernon says:

            Oh, that’s good to know. and thank you for that info. I will do that. Gosh I hope it helps. It’s so hard to get anything done with my computer so slow! 🙂

          • magsx2 says:

            If you can let me know if it works for you, if not if you can tell me the browser you are using, we may try something else.

          • Linda Vernon says:

            Well, I’m happy to report that cleaning the cookie cache helped alot, but I wonder if this comment will end up in spam? Can you let me know? Thanks Mags for your help!

          • magsx2 says:

            I am happy to hear that cleaning out of the cookies done the trick. But your comments are still going to spam, this is a WP problem, as I said you are not the only one it is happening too. Hopefully WP will sort this out, browsers are easy to fix, but WP is a different story.🙂

          • Linda Vernon says:

            Darn it! I’ll check around and see if there’s anything that can be done! Gosh that’s maddening! Hopefully it will be fixed soon. 🙂

    As usual, nice one.🙂

  5. susielindau says:

    What weird fish! Love it!

    • magsx2 says:

      Hi susielindau,
      They are a bit weird, but pretty in their own way.🙂

      Your comment went into the spam box, this is happening to a few people, so if you find your comment doesn’t appear on some blogs, that is why.

  6. reb says:

    Fascinating fish … so full of colours🙂 Didn’t even have an idea they existed..Very nice post..

  7. I had no idea they changed colors. Wow. You always bring the most fascinating facts to us.

    • magsx2 says:

      Hi writingfeemail,
      I think all the different species of cuttlefish change colour, it is just a lot more noticeable in these ones because of their size.🙂

  8. Lynn says:

    Life at sea is fascinating.Is another world inside this one.
    Lovely!

  9. Arindam says:

    Hi Mags,
    Great post. It made me laugh when I read that, “Males use these different colours to attract a female”. Lucky creatures!🙂

  10. niasunset says:

    Oh My God, like a science fiction… I haven’t seen this amazing fish before… WOW! Thank you dear Mags, Love, nia

  11. Windsmoke. says:

    I like the way he changes colour even to the extent that he would look like a rock resting on the seabed🙂.

  12. I want to be able to change colour like that…🙂

  13. Sea animals are very fascinating! I would love to swim in a nice coral reef someday and observe the fish swimming around🙂

    • magsx2 says:

      Hi Any Lucky Penny,
      Coral reefs are beautiful, there are just so many different types of fish that live around the reefs, and so many colours as well.🙂

  14. That is crazy how fast they change. Kind of an ugly thing otherwise.

  15. Wow! That is absolutely incredible! For me, cuttlefish were just dried up white things hanging in bird cages. I never knew that they were like that.

    Fairy Bower! I used to go there sometimes when I was a teenager. I didn’t like the sand very much because it was a lot coarser than the sand at North Steyne (which is Manly too) where I usually went to the beach. Fairy Bower was in a little protected bay which was why the sand was so coarse as the waves didn’t pound all the broken shells into fine sand. It was sheltered from the wind too so was a good place to go when the weather was cooler.

    Did you know that Manly was named after the “manly” appearance of the Aboriginal People who lived there? Can’t remember who named it now. But it was very early on, around Captain Phillip’s time, I think. Might even have been he who named it.

    • magsx2 says:

      Hi Lady Marilyn,
      Yes they are certainly different. There are over 100 different species of cuttlefish, not that much difference in the species, except for this one, only because of its size.

      I haven’t been for Fairy Bower for a long, long time, no doubt it would look a bit different than when I remembered being there.
      No I didn’t know that about Manly, very interesting.

  16. aFrankAngle says:

    Love the fact that the camera was able to catch it changing color. Also interesting how it sounds like a person breathing in scuba gear.😉

    • magsx2 says:

      Hi Frank,
      I also thought it was a great video, it was definitely the best video that actually showed the changing colours. There was another video I was also going to put up as well that I thought would go well with this one, even though embedding was allowed, when you clicked on the video in the blog, it just showed up blank which was a shame it also was a bit different.
      If you would like to have a look at the video it only goes for 34 seconds.

  17. These are so amazing. My oldest got a beautiful picture of a cuttlefish when he went scuba diving in Indonesia last summer, right when the fish turned bluish pink. They are amazing.

  18. First time I have seen a video clip on our Cuttlefish
    Great informative blog and clip

    Amazing colour changing/camoflage.

  20. That is so cool! Definitely designed by nature! I have never seen anything quite like it. Amazing how fast it changes colors!

  21. Selma says:

    It is enormous. Imagine if we could change colours like that – you would never have to worry about your shoes not matching your outfit. Very cool!

  22. Joanne says:

    What an incredibly cool fish! I loved watching him change colours as he swam around. It’s also very relaxing to watch an underwater scene like this.🙂

  23. Barb says:

    That fish changes color like I change my hair color. Sometimes I get the same hues, too. Fun post.

  24. hotlyspiced says:

    I didn’t know cuttlefish could change their colour. That’s really interesting. I’ve seen cuttlefish thingies in bird cages that they use to sharpen their beaks. xx

  25. Elyse says:

    So cool Mags. Thanks!

  26. They are such extraordinary creatures, quite beautiful in their own way. Scientists still know very little about octopi and cuttlefish, these creatures may well be very intelligent. WordPress is also doing strange things to me – my blogs were linked with Facebook so each blogpost should go automatically through to FB – now WP has stopped this, but the upside is that I’m no longer bombarded with spam mail via Facebook:)

    • magsx2 says:

      Hi mariathermann,
      They certainly are.🙂
      There are a lot of changes going on at the moment with WP it is maddening as they are doing whatever it is they are doing.

  27. A colorful predator – an underwater chameleon!

  28. lolabees says:

    Wow! I am constantly amazed by this planet (thanks to all of your posts!) That is so cool how it change colors like that. It’s how you’d imagine an alien being.

  29. Gregoryno6 says:

    Another underwater resident who’s good with colours.

  30. tempo says:

    ..and when you piss them off they go RED and have at you… (when you accidentally hook one on a fishing line) The largest breeding colony in the world is just a few KM from here and I’m sorry to say the SANTOS petrochemical plant has possibly poisoned them off with 10 years of oil leaks. In a bid to finish the job BHP is trying to force us to allow a loading zone right in the middle of the breeding zone. Our government has folded to the pressure and looks like allowing the big companies to continue polluting despite the public outcry.

    • magsx2 says:

      Hi tempo,
      Yes I actually read something about that in the papers awhile ago. I think there were some photos of protesters out there if I remember correctly, I went looking for the article I read but couldn’t find the one with the picture in it. We can only hope the worst does not happen.

  31. starlaschat says:

    That was really cool amazing. I nocticed that at times it would really bend in, great find. :+)
