A Blue Green Treefrog

An interesting color mutation was found in a green treefrog in Florida: it's blue. From the News-Press:

"A green treefrog recently discovered and captured at Corkscrew Swamp Sanctuary in Collier County is an amphibian of a different color — blue.
"The extremely rare blue green treefrog was found the weekend before Thanksgiving and has been an object of fascination for sanctuary staff and photographers." ...
"In scientific terms, the blue frog is axanthic, which means it lacks yellow pigment.
"Green treefrogs produce a layer of yellow pigment and a layer of blue pigment, and the two combine to make green.
"Something happened genetically to this frog: The genes that produce yellow are absent, and the genes that produce blue — that would be the blue genes — are present, so the frog is normal in every way except color." ...
"Somehow the frog survived and now lives in a terrarium, eating crickets and being blue, until Corkscrew officials decide what to do with their rare find — options include release."
