Description

This is a Green Tree Frog who has a genetic abnormality in which yellow pigment is not produced. Below the frog's epidermis or the outer layer of skin, there are three layers of cells called chromatophores. The bottom layer consists of cells which produce melanin which appear black or brown. The middle layer contains cells which are crystalline, gray in color but which appear blue when reflected back through the skin. This reflective layer is responsible for the iridescence in frogs. The top layer produces yellow pigment.Take away the yellow and you have blue. There appears to be some yellow pigment in the nose area of this frog which was captured in a wetland environment located in Woodbridge Virginia.
