![]() ![]() Semiterrestrial tadpoles spend most of their life out (or partially out) of water, inhabiting wet rock faces and rivulets (Altig & Johnston, 1989). We infer that the observations we present are explained by development being associated with aspects of terrestrialization and endotrophism. These changes seem to be associated with adaptations to life in the peculiar habitats where the tadpoles thrive. miliaris, in order to document and discuss alterations in the ontogeny of several larval structures. ![]() Herein we present a study of the tadpoles of C. Cycloramphid tadpoles have aspects of their morphology distinct from those of pond and stream dwellers they hatch in more advanced stages of development and have typical tadpole structures, either in a modified form or absent. Whereas some cycloramphid tadpoles are exotrophic, quasi-terrestrial and thrive in films of water that flow over rocky outcrops, others are endotrophic, terrestrial and complete their development outside the eggs laid on the forest floor, under logs or in crevices. Frogs in this family have peculiar spawning sites and developmental biologies. We studied the development of two species of the Neotropical family Cycloramphidae. Several generalizations have emerged but it is unclear whether they represent the diversity of the entire group. Anurans have served as models in evolutionary studies on reproduction and development. ![]()
