Well, I hope everyone is having a great week so far.\u00a0 Today’s Wild Fact is going to be confusing because it is about a fish that isn’t actually a fish.\u00a0 That’s right, the cuttlefish is not actually a fish.\u00a0 It is a mollusk, so similar to an octopus or a slug. I know it is mean of me to try and trick you but I am not the one who named this fish…errr, I mean mollusk.<\/p>\n

If you can remember the mimic octopus fact (if not you can check it out here<\/a>) you will know that these mollusks’ were able to change colour and shape.\u00a0 Well, the cuttlefish is also able to change it’s colour and even the texture of its skin.\u00a0 Again this is used as camoflage to protect themselves from predators.\u00a0 As well, they will use flashes of colour to communicate with other cuttlefish in the area.<\/p>\n

If any of you own a budgie then you may be familiar with the term “cuttlebone” which is used to provide calcium for the little birds.\u00a0 Tweety may love it but this cuttlebone has a much greater purpose when it is inside the living cuttlefish.\u00a0 The cuttlebone allows the cuttlefish to maintain buoyancy.\u00a0 This bone is unique to cuttlefish and varies in size and shape among various species.\u00a0 Although, I keep calling it a bone, it is mostly composed of aragonite which is similar to the endoskeleton of coral. The interesting part of the cuttlebone is the fact that it is a chambered gas-filled shell.\u00a0 Cuttlefish are able to regulate their buoyancy by changing the gas to liquid ratio in the cuttlebone.\u00a0 If humans had bones like this then we would never have to worry about wearing a life jacket.\u00a0 We would just need to increase the level of gas in the “cuttlebone” to make sure we stay floating.<\/p>\n

Cuttlefish Fast Fact:<\/strong> Cuttlefish have some of the most developed eyes in the animal kingdom.\u00a0 Yes, an animal more closely related to a slug then to a human have some of the most developed eyes.\u00a0 Although, they can’t use their eyes to see colour they are polarized which helps them see contrast in the water column.<\/p>\n","protected":false},"excerpt":{"rendered":"
