Resumen:
The South American frogs of the family Ceratophryidae (three genera, twelve extant species)display unusual larval diversity and developmental variation despite rather similar adults. Manyadult features of ceratophryids are associated with terrestrial/fossorial habits and resistance todesiccation; however, adults of the genus Lepidobatrachus are aquatic. Morphological novelties have evolved in the ceratophryid feeding mechanism that makes them capable of feeding on exceptional large prey (i.e. megalophagy). Lepidobatrachus is unusual in having less  ecomorphological differences between its larvae and adults than virtually all other anurans. Some unique features are differentiated in the tadpole and then exaggerated in the adult (e.g., a posterior displaced jaw articulation) in a manner unseen in other anurans. Both the larvae and the frog are similarly able to capture large prey underwater. The article reviewshow shifts in developmental patterns have led to a novel way of life for both larval and adult Lepidobatrachus spp.
