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