Cuttlefish are awesome

My brain is tired, my body is tired, and after a few mini-crises I'm just pissed. This is one of the few things I actually enjoy doing and I've been unable to do it.
EY! This is BULLCRAP!
Any-way...
Cuttlefish

Today we're all going to take a break and enjoy one of the aquatic world's more interesting creatures, the cuttlefish! (Which isn't actually a fish.)
When I first heard the name of this creature, long long ago, my first thought was "what the heck is a 'cuttle'?" This is because I had not learned to swear, you see. A bit of research later, and it seems the word has its origins in the middle German term "kudel" or pouch, which is indeed what the creature resembles.

That is, unless you read any Lovecraft, then then all look like little severed Cthulhu heads swimming about.

These little guys are members of the order Sepiida, why "Sepiida"? Think "sepia" as in as in "Hey look! That thing makes ink! GET IT!" That right folks, we used to use these guys as inkpots, now we just use the ink for cooking.

This is pasta. I actually want to try this...

As my cuttlefish knowledge-quest progressed, I learned some facinating things:
  • Cuttlebones are made of porus calcium carbonate, and helo the cephlopod maintain bouyancy. Squids don't have them, and almost all of ys have seen them already.
    "Where?" You ask. They're parakeet toys! The great old ones are going to be SO pissed.

  • Their W-shaped eyes are incredible. Although they look superficially similar, this is actually an example of convergent evolution. They can't see in color (ironic, ain't it?), but their ability to detect the polorization of light means they can see in much higher contrast than the pathetic air-breathers.

Despite the aswesomeness of these things, one element gets me more than anything else, their ability to change color and use gestures to communicate.





Is this not awesome‽
