Pupil dilation in frog

[TypingMonkey]

Ok thanks for the reply. I didn't know if he was sleeping or not because I heard that they sleep with their eyes closed. But I think you are right because light doesn't seem to make them smaller they actually get bigger when the light comes on, that's when I feed it so... Am I the only that gets this though or anybody else get this also?

Some frogs close their eyes to sleep - African Bullfrogs for example. Some don't - I've noticed my Gray Tree Frogs and Horned/Pacman Frogs don't close their eyes to sleep, they just shrink their pupils.
