Specifically, these frogs occur in Mexico, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama, Colombia, and Ecuador.

[3] H. fleischmanni are small and arboreal frogs that lives in lowland and mid-elevation forests of Central and South America.

They are carnivores and they eat small insects such as crickets, moths, flies, spiders, and even other smaller frogs.

Also known as the Northern Glass Frog, this frog's physical features include primarily green skin, which also reflects visible light typically at 400 nm to 700 nm,[5] pale yellowish spots, yellow fingertips and translucent skin covering its stomach.

A sheet of guanine stretches over several internal organs, but leaves others parts such as the liver exposed for viewing as it only covers half of the frog's underbelly.

[6] There have been more than 100 reported glass frogs throughout Central and South America, and 13 species can be found in Costa Rica.

[4] They have a very wide geographic distribution from Mexico to Ecuador and Suriname and are one of the most altitudinal species of their genus (approximately sea level to above 1600 m).

These frogs tend to lay their eggs on lower branches, the bottom of leaves and near flowing water.

In fact, the difference in acoustic properties of the calling sites due to the physical characteristics of the environment indeed affects the success rate of courtship and territory protection.

The pattern on the underside of the leaves was more consistent: at 50 and 100 cm, the sound in the front was always louder than that from the back, regardless of leaf size.

Male also tries to find a place over the main stream channel, thus the calling site is usually close to the water, about 0 to 6 meters.

[4] While conspicuous vocalization helps male H. fleischmanni attract female individuals, it also increases their risk of exposure to predators.

[6] From May to September, which is the breeding season of the H. fleischmanii frogs, females H. fleischmanni will constantly appear for mating.

Female H. fleischmannis stop moving around vegetation close to calling male frogs.

Due to the large number of its natural predators, roughly 80% of the clutches are eaten and/or destroyed.

For instance, some risks the eggs face are infections by fungus, or being eaten by larger predators such as crickets and possums.

The tadpoles that fall into the water usually remain hidden in debris at the bottom of the stream.

However, when the tadpoles reached the orange stage on the eighth and ninth days, they will have enough ability to survive on their own.

[11] Female H. fleischmanni lay and deposit eggs close to the calling site so they can be defended by males.

[8] A fringe-lipped bat, Trachops cirrhosus, is known to focus its attention on calling H. fleischmanni frogs.

Some animals, such as birds and snakes, have a presence in their bodies that helps them increase their sensitivity to near-infrared rays at night.

Known geographic regions indicated their effectiveness in differentiating H. fleischmanni into three apparently isolated clades by working as a barrier to dispersal.

Sea level and climate oscillations during the Pleistocene also had a strong influence on the structure and population of the glass frog clade.

[16] Artificial affections on environmental interventions may promote the growth of algae and bacteria in streams.

[8] Moreover, natural or anthropogenic environmental noise can mask the acoustic signals produced by animals.

A large part of the colony of the glass frog Hyalinobatrachium fleischmanni (Centrolenidae) overlaps with noisy urban areas, which affects the species' acoustic communication.
