Hyalinobatrachium fleischmannithe Fleischmann’s glass frog or northern glass frogis a species of frog in the family Centrolenidae. It is found in the tropical Americas from southern Mexico to Ecuador. Notice that this and related species have often been confused with each other, and the exact distribution depends on the source.

The specific name fleischmanni honors Carl Fleischmann, a collector in Costa Rica in the s. Glass frogs have similarities to tree frogs. They look very close to the naked eye except glass frog’s eyes point forward and are golden.

During the day, these frogs camouflage themselves under leaves but above water. They have a green semi-translucent color with yellow translucent hands.

Their skin has dots which matches that of the leaves in the area. When confronted or approached, they tend to freeze up and not move. Hyalionbatrachium is not specifically known what the glass frog eats, but it is assumed that they feed on small insects.


They also possess a white vocal sac that can be used to produce sounds for mating.

Male frogs have a noticeable hook protruding from its spine, presumably used to fight other frogs, defend its territory or the eggs. They are fierce fighters who will occasionally engage in a wrestling match with other intruding frogs. The female species are slightly larger and lacks this particular feature. Adults tend to be more active during the night when there is rain to keep their skin moist and from drying out.

However, strong rains can kill them because their bodies are so fragile. A simple direct shot from a raindrop has been known to kill a glass frog. Fleischmann’s Glass Frogs live near fast streams. In Costa Ricathese frogs live in lowland wet forests, rain forests, and even in higher elevations.

They do not like dry areas such as the northwestern lowlands, high mountains, or coasts.

Northern glassfrog (Hyalinobatrachium fleischmanni)

Of all the glass frogs in Costa RicaFleischmann’s glass frogs are the most populous. These frogs tend to lay their eggs on lower branches, the bottom of leaves and near flowing water. About 18—30 eggs hyalinbatrachium be laid, and the male frog would stand guard over the eggs to protect them from predators until they hatch, and the tadpoles drop into the water. Should any potential threats not back away, the frogs would fight until a winner is determined.

The victor would be able to reproduce with the female. The number of eggs is dependent on the time of year they are laid.


The male frog takes precautions to keep his eggs safe, such as defending them, or urinating on the eggs to ensure that they do not dry out. The eggs hatch after approximately 10—15 hyallinobatrachium.

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

Their growth is time-consuming, and it takes between 1—2 years for the tadpoles to fully mature. Some risks the eggs face are infections by fungus, or being eaten by larger predators such as crickets and possums. From Wikipedia, the free encyclopedia.
