AbstractMost frogs have weak jaws that play a relatively minor role in tongue‐mediated prey capture. Horned frogs (Ceratophrys spp.), however, follow the projection of a large tongue with a vice‐like grip of their jaws to hold and immobilize prey. Prey include relatively large vertebrates, which they may restrain for minutes to possibly hours.

The present study analyses, by transmission electron microscopy, vitellogenesis in two anuran amphibian families: Leptodactilidae (Ceratophrys cranwelli) and Bufonidae (Bufo arenarum). These differ in the type of stimulus that sets off their reproductive period, pluvial changes being the trigger in C. cranwelli and temperature increase in B.

Two related species of the genus Ceratophrys (C. ornata and C. cranwelli) were studied by immunological techniques in order to find non-morphological characters which would allow to classify them more precisely. Bidimensional immunodiffusion of serum proteins showed extensive crossreactivity between both species, thus revealing their close relatíonship.
