Cephalopods

Various colours and shapes in the Cephalopod class.




Next thing to work on is some examples of how they use the colour changing behaviour. The Giant Cuttlefish, (which can be seen on the lower left of the above picture) is capable of changing its colours to look like a female in order to fool competitive males into dropping their guard. Then there are species that display "warning colours" such as the brightly coloured but highly poisonous Blue Ringed Octopus(right hand side in the picture below). Bobtail squids (left in the picture below) light up the lower half of their bodies in order to blend in with the sky above and make themselves invisible to predators. The website has been updated with both images.




One more thing, leenacia pointed out this wonderful project by a scientist for the Year of Biodiversity 2010. I will definitely be submitting some species.
