glass frog behavior

Character evolution seems to be complex, with multiple gains and/or losses of humeral spines, reduced hand webbing, and complete ventral transparency. [5], Glass frogs are generally small, ranging from 3 - 7.5cm (1.2 - 3.0) in length. He remains there until she lays her eggs. [2] However, they left a heterogeneous group of species in the genus Cochranella, defined just by lacking a humeral spine and a bulbous liver. The male wraps his front legs around her and hangs on just behind her front legs. Hyalinobatrachium valerioi glass frogs are carnivores, their diet mainly including small insects like crickets, moths, flies, spiders, and other smaller frogs.[9]. [2] Since the publication of the extensive revision of the Colombian glass frogs, several other publications have dealt with the glass frogs from Venezuela, Costa Rica, and Ecuador. The winner is the one that can knock the other off, or that can manage to scramble onto the leaf's surface and flatten down his body on it. Glass frogs are arboreal, meaning they mainly live in trees, and only come out for mating season. Others that live in places with changing weather usually mate only at certain times. In 2004, for instance, researchers from the University of Kansas announced a new species from northwestern Ecuador. [2] That paper was the first of a series of contributions dealing with the glass frogs from Colombia that led them to describe almost 50 species of glass frogs. The eggs are usually deposited on the leaves of trees or shrubs hanging over the running water of mountain streams, creeks, and small rivers. "Glassfrog" redirects here. Like the Nicaraguan glass frogs, which live in Nicaragua, Costa Rica, Panama, Colombia, and Ecuador, they may mate only on nights following heavy rains. Eggs come in different colors, depending on the species. This, combined with their transparent bodies, makes them very difficult to spot for people or for predators.

The vast majority of species in this family lay their sticky eggs either on top of or on the bottom of leaves. If another male happens to enter a glass frog’s breeding territory, it warns its mate by producing a very peculiar, low-intensity sound. Infrared reflectance may confer adaptive advantage to these arboreal frogs both in thermoregulation and infrared cryptic coloration. People are still discovering new species of frogs, including glass frogs. The frogs’ translucency is … This, combined with their transparent bodies, makes them very difficult to spot for people or for predators. The female Nicaraguan frog stays with her clutch for at least the first night. One detail is that it can camouflage. Since the rainforest and cloud forests are so full of plants and trees, the tiny green frogs can easily stay out of sight if they sit on a leaf and do not move. However, hylid tree frogs have eyes that face to the side, whilst those of glass frogs face forward. At night, however, they are very active. The monophyly of Centrolenidae is supported by morphological and behavioral characters, including:1) presence of a dilated process on the medial side of the third metacarpal (an apparently unique synapomorphy); 2) ventral origin of the musculus flexor teres digiti III relative to the musculus transversi metacarpi I; 3) terminal phalanges T-shaped; 4) exotroph, lotic, burrower/fossorial tadpoles with a vermiform body and dorsal C-shaped eyes, that live buried within leaf packs in still or flowing water systems; and 5) eggs clutches deposited outside of water on vegetation or rocks above still or flowing water systems.
