Tyler's tree frog ventral
NB. not captive....a night time visitor to the house, indeed a high-up second floor window. These frogs are well used to climbing and in fact do not like water that much. It is native to eastern Australia, occurring from southeast Queensland to the south coast of New South Wales. It is generally a coastal species and is not found inland.
This was 4 cm from tip of snout to rear end, so not fully grown. I was able to stand on a chair and get a look at the eyes to confirm identification - similar looking Tyler's and Peron's have pupils which appear cross-shaped which this frog had, but Tyler's frogs do not have the strong black and yellow marbling on the inside of the legs and armpits and has only faint yellow/orange/brown marbling as seen here.
Tyler's tree frog or the southern laughing tree frog is an arboreal tree frog. It is native to eastern Australia. It occurs from southeast Queensland to the south coast of New South Wales. It is generally a coastal species and is not found inland.
