Aperture of the human eye?

I was looking at Matt Crumin's site which is relay excellent. (Using E-M5). I found the link through 4/3rumors. Matt has a little pull down in the corner that gives an interesting factoid:

"The f-number of the human eye varies from about f/8.3 in brightly lit conditions, to about f/2.1 in dark conditions."

"To work out the focal length of the human eye, you would need to take into account the light-reflecting properties on liquids in the eye."

Really interesting. What do you think? Is this for all human eyes? It would be very interesting to know what the aperture for other species eyes would be.

What if the hokey pokey really is what it's all about?
