One of the really neat things about most albinos is the ability to see through their skin and see different organs.
Today, while I was feeding my female Nebraska albino radix(Rita) I was able to see a number of dark areas along her lower 1/3rd. From their shape I would say it's a load of little scrubs.
She's really been eating and putting on the weight(200g) On 4/4/2010 she was 184g.
