I wanted to know if the coloration/body markings change much as they grow from metamorph/froglets to adult frogs. im asking about green frogs (rana clamitans) in particular. my froglets all seem to be a uniformly dark dull brown/olive green color (more of a green when under good lighting) and was hoping they would have some bright green coloration (particular around the heads). im looking at images of adult green frogs and they all seem to have at least a little bright green just above the lip so my guess is that they do?
