The Orange-eyed tree frog is a uniform bright green above, occasionally with yellow spots, and bright yellow on the underside. The front sides of the arms and legs are green, while the underside is yellow or white. The thighs may be blue/purple to blue/black in colour in adults. It has golden eyes at the centre, which change to red towards the edge of the eye. The intensity of the eye colour is variable between frogs. The tympanum is visible, and a mature frog reaches a size of 65 mm.
Scattered distribution along the Queensland and New South Wales coastline, from Prosperine in the north to mid-eastern New South Wales.
Life History, Abundance, Activity, and Special Behaviors：
Usually associated with coastal rainforest or wet sclerophyll forest. It spends much of its life high in the trees and is usually only seen in association with heavy rain when it descends to breed. Also found in association with flooded drains, water tanks and quarries at this time. Breeding is in spring and summer (October – February) after heavy rain when they congregate in and around flooded areas and mountain streams. Calling, amplexus and oviposition occurs in permanent and semi-permanent shallow pools in or besides streams and eggs are laid singly or in small clumps entangled in vegetation.
A large species of frog reaching up to 6.5 cm in body length. It has a bright green back. The belly is yellow. The pupil is horizontal, and the iris is orange or red. The backs of the thighs are purple, and the hands and feet are yellow. Fingers are three-quarters webbed and toes are nearly fully webbed, both with large discs.
Breeding Biology
Eggs are laid as small clusters that are attached to vegetation at or near the surface of temporary pools, stream pools, and permanent ponds. Tadpoles can reach a total length of up to 5 cm, and are grey-brown or dark brown in colour. They often remain at the bottom of water bodies, and take at least two months to develop into frogs. Breeds during spring and summer after heavy rain.
I AM AN INSECTIVORE
Like many other frog species, orange-eyed tree frogs are insectivorous and the majority of their diet consists of crickets, moths, and flies.
ORANGE-EYED TREE FROGS ARE SOCIAL
The orange-eyed tree frog is a solitary amphibian and only shares space with other frogs during mating season.
ON THE DEFENSE
Orange-eyed tree frogs use a defense mechanism called “startle coloration.” Startle coloration refers to bright coloration on an animal’s body that can be used to startle or frighten predators. An orange-eyed tree frog’s eyes can be used for this purpose. Additionally, when this frog closes its eyes, they are able to camouflaged themselves very well with their surroundings.
The orange-eyed tree frog, scientifically known as Ranoidea chloris, is a captivating amphibian that enchants both researchers and nature enthusiasts alike. This species, characterized by its striking orange eyes and vibrant green skin, is primarily found in the lush rainforests of Australia and New Guinea. Understanding the life cycle and habitat of this remarkable frog offers valuable insights into its ecological role and the environmental challenges it faces.Life CycleThe life cycle of Ranoidea chloris is a fascinating journey that encompasses several distinct stages: egg, tadpole, juvenile, and adult.
- Egg Stage: The reproductive cycle begins with the female laying her eggs in shallow pools or on the leaves above water bodies. These eggs are typically laid in clusters, surrounded by a gelatinous substance that provides protection from predators and environmental hazards.
- Tadpole Stage: After a period of incubation, which lasts approximately one to two weeks, the eggs hatch into tadpoles. These aquatic larvae are characterized by their elongated bodies and lack of limbs. They possess gills for respiration and feed primarily on algae and detritus found in their aquatic habitats. During this stage, tadpoles undergo significant morphological changes as they prepare for metamorphosis.
- Juvenile Stage: As tadpoles mature, they begin to develop limbs and lose their tails, transitioning into the juvenile phase. This metamorphosis typically occurs within six to eight weeks after hatching. Juveniles are more terrestrial than their aquatic counterparts and start to explore their surroundings, gradually adapting to life on land.
- Adult Stage: Upon reaching adulthood, Ranoidea chloris exhibits distinct physical characteristics that differentiate it from its juvenile form. Adults are known for their vibrant coloration, which serves as both camouflage in their leafy habitats and a warning to potential predators about their toxicity. Adult frogs are primarily nocturnal, emerging at night to feed on insects and other small invertebrates.
HabitatThe habitat of the orange-eyed tree frog is intricately linked to its life cycle and overall survival. This species thrives in humid tropical rainforests where temperatures remain consistently warm throughout the year.
- Rainforest Ecosystems: The dense foliage of rainforests provides an ideal environment for Ranoidea chloris, offering ample cover from predators and abundant food sources. The high humidity levels in these ecosystems are crucial for maintaining skin moisture, which is essential for amphibians due to their permeable skin.
- Breeding Sites: Shallow pools, streams, and temporary water bodies serve as vital breeding sites for this species. These habitats not only facilitate reproduction but also provide a safe haven for developing tadpoles.
- Threats to Habitat: Unfortunately, the orange-eyed tree frog faces numerous threats that jeopardize its habitat. Deforestation, driven by agriculture and urbanization, has led to significant habitat loss. Additionally, climate change poses a serious risk by altering rainfall patterns and increasing temperatures, which can disrupt breeding cycles and food availability.
the orange-eyed tree frog (Ranoidea chloris) exemplifies the intricate relationship between an organism’s life cycle and its habitat. Understanding these dynamics is essential for conservation efforts aimed at preserving this enchanting species and its rainforest ecosystem. As we continue to explore the natural world, it is imperative that we advocate for sustainable practices that protect both the orange-eyed tree frog and the rich biodiversity of our planet’s rainforests.
