why exactly are you surprised by the red pupils? I mean, their blood still IS red (isn't it? <.< ), so you probably see through the eye onto the blood vessels on the other side..... every albino has it like that, could imagine something like that here too?

Thing is... they're not a "full" albino. So yeah, all animals have red in their eyes, but most have black pigment too. Most leucistic animals I know of have black pupils. I'm wondering if it's because of the location + white skin that the light can still penetrate enough to look red.

probably ^^
I don't know enough of em to be able to say something to that, sorry ^^'

.... I should restate that. The pupil really a transparent window (covered by the lens) into the globe of the eye, which is full of clear vitreous humor. There is no blood in there or in the lense. Behind that is the retina which has a pigmented layer behinds the rods and cones in a normal eye. I thought that's what tends to make pupils dark, as I believe it is a brown/black color.

well, yes, of course, but BEHIND the eye itself is skin which contains the photo-sensitive cells - and those are supported with blood. and since the clear liquid is, well, clear, it can shine through if the pigmented layer isn't pigmented. as it is in full albinos. since those generally lack any kind of pigment :P
