Hahhahaha, now that I have your attention, LOL
Just an interesting observance. I always see my different species of frogs shed and eat their skin.
Anyway I just the other day watched lakoda shed a big hunk of skin, the entire back piece, and it was laying on the water dish.
Squashy the adult male went right over and ate the whole piece. ~And NOT from the lack of food, 
Like I say this was a very good size hunk, and he ate every bit.
Now frogs do it for the nutrients, so I suppose collareds do it for the same reason. 
~ Just trying to get under your skin, hahhahahahaahha,~
actually, thought it was quite interesting !
