Quacking Frog - Crinia georgiana
A small frog usually between 30-40 mm (excluding legs) with an amazing camouflage ability. Its striped coloration blends well with the swampy sedge vegetation where it normally lives, but the skin can be smooth, folded and/or granular to totally break its outline (above is a photo where the frog is central and makes up most of the picture, but is almost invisible). If you do spot one, it is easy to recognise by the golden or red upper eyelids and often bright red groin. The belly and chin tend to have a random distribution of darker spots over a brown/grey background. The Quacking Frog also has a distinctive call that can be heard here: http://frogsaustralia.net.au/frogs/display.cfm?frog_id=6
