Parental Care in Glass Frogs

The glass frogs, are Anuran amphibious of the family Centrolenidae, this tiny animals present in the majority of his species a light green dorsal coloration, and his ventral part is almost always transparent, because of this special feature, easily you can see his intern organs such as his stomach, the liver, his bowels, and also you can see the beat of his heart. The majority of the centrolenid species has parental care, which means that father, mother, or inclusive both parents stay with their eggs and take care of them until the juvenile frogs emerge.

















This special behavior, has to do whit terrestrial reproduction, unlike the majority of the amphibias, the glass frogs put his eggs under the leaves. Generally the males stays whit them day and night protecting it of potential predators such as wasps, insects, or other amphibians, also the males prevents the desecation of his eggs producing continiously a gelatinous liquid whit special glands that are located in the back of the animal, also this liquid prevents possible fungi and bacterial infections. 

They reproduction behavior is well documented, the male stays exposed over a leaf or a stone, and he begins to call, this call is named a reproductive song, the male who song more louder and faster will atract more females, then the male do a reproductive "hug" called amplexus to the female, once her is fertilized, she puts a bag of eggs over or under the leaf where the male was. 

After copulation, he stays close to the eggs whitout touching them, or over the eggs, it depends of the specie, generally male protects the eggs at night, and watch them from a near place, but has been cases that he stay whit the eggs day and night. The male is in  alertness but he does not move, his metabolic rate descends according to face all the dangers that he could be exposed (solar radiation, lack of food, dehydration, etc.).

Once the eggs emerge (14 days on average) and the male conduce them to the water and there he finished their work only for sing another reproductive song...
