Anuran feeding after hypophysectomy
General and Comparative Endocrinology, 1971Spontaneous feeding continued in toads (Bufo americanus) and frogs (Rana p. pipiens) for 8–30 days following removal of the pars distalis. The toads always died within a few days after cessation of feeding. It is concluded that the pars distalis is not as essentially involved in normal feeding mechanisms as recently postulated by Dierickx.

The regeneration of limbs in adult anurans
Development, 1967ABSTRACT The regeneration of limbs, after simple amputation, in two families (four genera) of primitive anurans was investigated. All produced hypotypic regenerates of varying size and degree of morphogenesis. Despite certain differences possibly related to phylogenetic affinities, both Discoglossidae and Pipidae regenerated in similar ...

Function of the Anuran Conus Arteriosus
Journal of Experimental Biology, 1974ABSTRACT The anuran conus arteriosus was studied by direct observation of its structure and function and by observing the effects of artificially induced contraction on the pressure pulse in the arterial arches. The beat of the anuran conus was found to close the outlet to the pulmocutaneous arches. The timing of the beat of the conus in

Neuromast topography in anuran amphibians
Journal of Morphology, 1987AbstractGeneralized anuran tadpoles across families exhibit a similar neuromast morphology on their heads, as follows: (1) all neuromast lines known for anurans are present; (2) within these lines total neuromast number ranges from about 250 to 320; (3) neuromasts form linear stitches composed of two to three, but sometimes up to five, neuromasts; (4 ...
