Sesamoids are skeletal elements rarely considered in studies of the vertebrate skeleton. In this work, we integrate ontogenetic data of anuran sesamoids in two species (Leptodactylus latinasus and Pleurodema cf. guayapae), ...

In amphibians, pigmented cells are present in several organs, composing an extracutaneous pigmentary system. Seventeen species from two families were studied to develop a protocol for pigmentary classification. The amount ...

Testes in anurans are a structure that posses distinct morphology and coloration. Spermatogenesis in these group is a complex and organized process that involves spermatogenic cysts progression through in the seminiferous ...

The development of the tetrapod pectoral and pelvic girdles is intimately linked to the proximal segments of the fore- and hindlimbs. Most studies on girdles are osteological and provide little information about soft ...

The liver is a well-defined organ regarding its functions; however, it may present morphological variations among species. Since anurans may be exposed to toxic substances in their environment, which can disrupt liver's ...
