## Abstract This study provides the first data on muscle activity patterns during active feeding in a larval anuran. Data regarding muscle function during gill irrigation and hyperexpiration are also provided. Electromyographic and kinematic data were recorded from six mandibular and hyoid muscles

## Abstract The lifespan of herbivorous __Rana pipiens__ larvae is โผ3 months, while that of carnivorous __Ceratophrys ornata__ larvae is only about 2 weeks. During metamorphic climax, the larval gut shortens dramatically, especially in __R. pipiens__, and its luminal epithelium is replaced by adult
Larvae of Ceratophrys ornata are carnivorous, have relatively short digestive tracts and continue to feed during metamorphic climax, in contrast to those of more typical herbivorous anuran larvae. The present study describes both histological and histochemical changes in the stomach, small intestine
