Question:
I know you're going to think I'm nuts but I have caught a bull frog that is a very bright blue when he sits above the water line for any length of time.When he stays under water his color changes to a very deep blue that virtually looks black.I have never seen this before and have been walking ponds for as long as I can remember. Any information would be helpful.

Replies:
Blue bullfrogs are a rare finding, but have been reported. These animals lack the ability to produce the normal yellow pigment in their skin cells.
