Cephalopods

Monday, Mar 15, 2010

Cephalopods are a family of invertebrates including octopuses and squids. Their amazing camouflage abilities, which are faster and more complicated than chameleons, include color shifting (even though they are color blind!), changing the texture of their skin, mimicking movements of other objects, and performing animations on their body [mbl.edu, nytimes.com].

Some male cephalopods use this trick to look like females so that they can mate with females that are guarded by males. This can be enough to even cause the male to sometimes guard that spying male... Although what if the guarding male gets horny?
