Update: 9 July 2008.

I've just learned that my tasty crustacean doesn't have quite the fastest movement of any animal (some ant can snap its jaws faster) but it is the only animal known to see Circular Polarised Light.
The story (I missed it when it came out in March) is at the Wired Science blog.
If you want to know what Circular Polarised Light is, then look at a related news story by the same writer, Brandon Keim, at Wired Science, where this photo came from.
Next time I get some, I'll look 'em right in the eyes before I cook ém.
