Thousands of years ago, green-eyed treefrogs separated in the northern and southern parts of Queensland and recently started breeding again.

Their geographic separation has caused a change in mating calls, that continues to drive the two types of green-eyed treefrogs apart.

[3] Scientists now use the green-eyed treefrog in their studies of speciation and evolution due to the mating habits of the frogs in Australia.

[3] When it comes to monitoring the current population, the best method to use is a photographic identification model, since dorsal patterns of the green-eyed frog is not shown to change over time.

[4] To help conserve the green-eyed treefrog population, monitoring and awareness efforts have been increased and an exhibit was created at the Chester Zoo in the United Kingdom.

While dark spotting appears to be found on the bottom of all adult green-eyed treefrogs, colors range from bright green to brassy on their upper bodies.

[2] The green-eyed treefrog's natural habitats are mainly subtropical, but can also include tropical lowland forests, as well as rivers and freshwater marshes.

Living near creeks and streams, their rust colored blotches tend to match the lichen covered rocks that line the bodies of water.

Though it mainly prefers dense wood, it also tends to like bodies of water located in clearings or pastures.

[6] Due to the males lack of vocal sacs, they have soft mating calls that can only be heard from short distances.

[6] Though the frogs have suffered some decline in past years, which can be blamed on a fungal disease, their numbers have come back stronger.

Scientists and researchers believe that this disease has been the main reason for many species extinctions and population decreases among frogs since the 1990s.

Besides fungal disease, habitat loss, pollution, and drought have also called amphibian populations to decline.

[8] The species experienced a chytrid-related decline in the 1990s and is classified as vulnerable under the Queensland Government's Nature Conservation (Wildlife) Act 2006.

[11] Peptides found within the skin of frogs, including the green-eyed species, are now being looked to for HIV virus prevention.

The chemicals found within their skin aren't pleasant for their predators, but can be very useful when fighting against bacteria, viruses, and fungus.
