The marbled frog (Limnodynastes convexiusculus), is one of the most interesting and mysterious ground-dwelling amphibians. It is also called the marbled marsh frog, and it is quite frequently confused with the spotted grass frog (Limnodynastes tasmaniensis), which was and still can be wrongly referred to as a marbled frog. Further confusion can be caused by their overlapping range of distribution as the spotted grass frog is also found in Queensland and South Australia, to which the marbled frog is a native species. The frogs of this species are famous for their call, which is considered to be a rapid series of loud honks, and the sound is usually made by the males of the species. Sometimes, the males call throughout the night, regardless of whether it has rained or not. The females are known for having special flanges for the construction of nests for their eggs, which they do by creating air bubbles and constructing a floating foam nest underwater in temporary pools to lay their eggs in.

The marbled frog has a somewhat restricted distribution and is native to Australia and southern New Guinea. In Australia, they are mainly found in the northern and northeastern parts. These frogs are commonly spotted, not only within their natural habitat but also in urban areas. This mostly occurs when it has recently rained very heavily. Thus, its population is considered to be stable and they are listed as Least Concern.

Marbled Frog Interesting Facts

What type of animal is a marbled frog?

The marbled frog is a type of frog.

What class of animal does a marbled frog belong to?

The marbled frog (Limnodynastes convexiusculus) is a member of the class Amphibia and family Limnodynastidae, which mainly consists of amphibians like frogs found in Australia and New Guinea. Therefore, this set of frogs is also sometimes referred to as the Australian ground frogs.

How many marbled frogs are there in the world?

Because it is so commonly found within its distribution, data concerning the exact number of these frogs in the world is very hard to quantify. However, its population is said to be stable and under no apparent threat.

Where does a marbled frog live?

The marbled frog is found in the wetlands of Australia as well as New Guinea, where it is mainly found in Indonesia and Papua New Guinea. This species lives in the northern and northeastern parts of Australia including Queensland and the Kimberley region. It also occurs in several national parks in northern Queensland, such as the Eurimbulah National Park. In New Guinea, it can be found up to the elevation of 164 ft (50 m), but in Australia, its distribution is spread across flat regions only.

What is a marbled frog's habitat?

This species is mostly ground-dwelling and is known to prefer a wetland habitat such as areas near marshes, swamps, ponds, and other low-lying areas that are exposed to flooding. They have also been found at night in urban areas after it has heavily rained. In their habitat, they will mostly be hidden in dense or submerged vegetation, at the base of grasses, among the debris, or in abandoned burrows of crabs. These places are usually where males call from. They are also usually located near small bodies of water for the females to construct a foam nest to lay eggs in.

Who does marbled frog live with?

Marbled frogs are said to live alone or solitary. Males are known to hide and call from behind submerged vegetation, and it is hard to actually see them. Sometimes, invasive toxic species like cane frogs are seen living in the same habitat, but this can have negative effects on the population of the native frog species like the marbled frog.

How long does a marbled frog live?

There is not enough data available regarding how long a marbled frog can live. However, some frogs like the goliath frog can live up to more than 20 years!

How do they reproduce?

Marbled frogs reproduce by sexual reproduction. The breeding season is usually from October to March for this species. The nest of the marbled frog, and other frogs of similar species, can be very unique. After mating, the females use the extra flanges on their hands to trap air bubbles from above the surface of the water and create a floating foam nest under the water. The eggs are fertilized and deposited in that foam nest. Tadpoles that emerge out of these are around 2.8 in (7 cm) in length, and black in color. These tadpoles then go through metamorphosis, which does not last long. After this, they finally grow into adult frogs.

What is their conservation status?

This species of frogs are commonly found within its distribution, and there are no threats to their population. That is why they have been classified as Least Concern by the IUCN Red List.

Marbled Frog Fun Facts

What does the marbled frog look like?

The marbled frog (Limnodynastes convexiusculus) can vary in color from olive green or gray to brown or light brown, with some dark, raised splotches. Their belly and throats are white, though males can have a yellow throat. Unlike most frogs, the feet and hands do not have webbed toes and fingers. This may be because their preferred habitat is on the ground. Their skin is usually slimy with mucous, which they are said to excrete if they are bothered and they feel in danger. Females usually have flanges on their fingers that come in handy when constructing floating nests, in which they deposit their eggs. Tadpoles are somewhat long and are completely black in color. These frogs look similar to the spotted grass frogs (Limnodynastes tasmaniensis), which are also olive green and gray in color, and found in South Australia.

It is also called the marbled marsh frog

How cute are they?

The dark splotches on the slimy bodies of these frogs may look a little unappealing. Hence, they cannot be considered very cute.

How do they communicate?

The males of this species are said to call from their hidden positions in submerged vegetation or abandoned burrows to attract females during the breeding season. However, males have also been found making these noises throughout the rainy season, the reason for which is unclear due to insufficient data and research. Their calls are repeated or recurring honks that sound like 'uk uk uk'.

How big is a marbled frog?

The adults of this species can have body lengths in the range of 1.8-2.3 in (4.5-6 cm). This makes them about two times smaller than the common frog. The tadpoles of the marbled frogs can also be slightly bigger in length than the adults at 2.8 in (7 cm).

How fast can a marbled frog leap?

There is not much data available about the speed and agility of marbled frogs.

How much does a marbled frog weigh?

The exact weight of the amphibians of this species is not known. However, the spadefoot toad, from the family Scaphiopodidae, is said to weigh only 1.7-3.5 oz (50-100 g).

What are the male and female names of the species?

The male and female frogs of this species do not have sex-specific names and are only referred to as the male frog or female frog.

What would you call a baby marbled frog?

A baby marbled frog can have different names depending on which stage it is in its life cycle. When they emerge out of their foam nests, they can be called larvae or tadpoles. Only after these tadpoles go through metamorphosis can they be called adult frogs.

What do they eat?

These frogs are most likely dependent on insects for their diet. However, they can be considered cannibalistic, as they are known to attack and consume other frogs if the opportunity presents itself.

Are they dangerous?

No, the marbled frogs are not considered dangerous and are pretty much harmless to human beings. However, they sometimes excrete slimy mucous from their skin if they are bothered. Some frogs are also known to carry salmonella, so it would be better to only observe them from a safe distance rather than trying to hold or touch them.

Would they make a good pet?

Though it is unclear if marbled frogs can be good pets, some frog species have been known to be great pets. However, it would be hard to replicate the natural habitat of dense, submerged vegetation in a captive environment.

Did you know...

Since marbled frogs consume other frogs, it can be highly dangerous for them to consume a frog that is toxic in nature. But a number of studies have shown that marbled frogs can be very resilient when a toxic species of frogs invades their nesting areas. When exposed to invasive and toxic species of toads, young frogs or tadpoles, when they were grown, eventually learned not to consume them and were less likely to attack them. This might be a great factor in the survival and stability of their population in their natural habitat over the years.

Does marbled frog go into hibernation?

Species like the marbled frogs are generally known to hibernate underwater during the dry season, and only come out when some substantial rainfall has taken place, and the ground is soft.

How did the marbled frog get its name?

The marbled frog is named after the dark splotches on its olive green or gray body, that look similar to the spots that are visible on a marble stone.
