Despite the fascinating parental care behaviors exhibited by amphibians, relatively few quantitative studies have been published on this class in comparison to birds and mammals. Six modes of parental care are recognized: egg attendance, egg transport, tadpole attendance, tadpole transport, tadpole feeding, and internal gestation in the oviduct. Whereas egg attendance and internal gestation in the oviduct are the only modes of parental care known for caecilians and salamanders, anurans display all six modes. Although parental care is widely distributed phylogenetically within the Amphibia, the percentage of species providing care is low. Postoviposition parental care has been documented in only about 5% of caecilians, 18% of salamanders, and 6% of anurans. Internal gestation in the oviduct probably occurs in about 75% of all caecilians, in 4 species of salamanders, and in 5 species of anurans. Parental care in amphibians is most commonly found in geographical areas of correspondingly high species richness.

Amphibianincludeanurans, urodelans and apodans. In all these groups of amphibians we come across with a great deal of parental care. Amphibians show several mechanisms to protect their eggs and developing young ones because of the they lay few eggs.

The female Icthyophis glulinosa will dig a hole in the moist soil near a pond. It will deposit eggs in it. Around this egg mass the mother will coil and. protect the egg mass from the enemies.

Inbiology, paternal care isparental investmentprovided by amaleto his ownoffspring. It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. Paternal care may provided in concert with the mother (biparental care) or, more rarely, by the male alone (so called exclusive paternal care).

The provision of care, by either males or females, is presumed to increase growth rates, quality, and/or survival of young, and hence ultimately increase theinclusive fitnessof parents.In a variety of vertebrate species (e.g., about 80% of birdsband about 6% of mammals), both males and females invest heavily in their offspring. Many of these biparental species are sociallymonogamous, so individuals remain with their mate for at least one breeding season.

Paternal care occurs in a number of species of anuran amphibians,[46]includingglass frogs.Exclusive paternal care has evolved multiple times in a variety of organisms, including invertebrates, fishes, and amphibians

Parental Care in Amphibians.Parental caremay bedefinedas all activities that are directed by an animal towards the protection and maintenance of its own offspring or those of a near relative. By comparison with birds and mammals,amphibiansgenerally have been thought to exhibit littleparental care.
