I have a frog (common Australian green tree frog - littoria
coerelia (sp?)) and have observed it changing colour on a
number of occasions. The colour changing could be a protective
adaptation to help the frog blend into the background (although
the colour changes seem to have nothing at all to do with the
colour of the frogs surroundings). Does anyone know what sort
of situations cause this type of frog (or other types of frog)
to change colour when it is not threatened by a predator?
