My new favourite animal

When I was younger people would sometimes ask what my favourite colour was, or what my favourite animal was. I don't know I guess that's just what you ask kids or what kids talk about at school. Anyhow I decided that my favourite colour was green in case anyone ever asked and that my favourite animal was the king cobra. I guess I thought snakes were pretty cool and that they looked awesome when they expanded their hood (or maybe I watched too much rikki-tikki-tavi).

Regardless, I had never spent any time reflecting on this choice and possibly dethroning (har har) the king cobra. Recently though, in one of my classes, the prof showed a short video of a cuttlefish blending into their surroundings. This piqued my interest because I had always liked chameleons and I actually knew very little about cuttlefish aside from this.

I have since learned that besides being able to change colours very quickly to match their environment, cuttlefish:

• have a cuttlebone which allows them to adjust their depth
• can see the polarization of light and can adjust the polarization of light that reflects off of them to communicate with other animals
• have w-shaped eyes
• have three hearts
• have fully developed eyes before they're born and can look around while they're still in the egg
• are the original creators of sepia
  
• have a large brain to body ratio
• have green-blue coloured blood

So after all of this I have decided that cuttlefish are my new favourite animals. It also might be time to reevaluate some of your "favourite" things and see if they've changed since you last made up your mind.
