Are you sure? youtube.com/watch?v=dgh6ABfdlAU shows a hawk's nictitating membrane moving from sidewise.

Could you check the correctness of my reasoning in the original post, including the use of duration of pregnancy?

I wonder why the duration of pregnancy (95 - 160 days for panda) doesn't enter the computation? Or is it included in the weaning time?

Thanks for the answer based on allometry. What's a good survey book on animal allometry? I've read Niklas' Plant Allometry for plant allometry.

So you are saying it is rather normal for mammals to have high rate of multiple births, and panda is just an example? If so, why human normally have single birth?
