Abstract
El disco abdominal de Atelopus es una estructura compleja que presenta tres regiones bien definidas así como varios músculos y ligamentos incertados en su superficie interna. Aquí se plantea la hipótesis que el disco abdominal presenta dos mecanismos para fijarse al sustrato: fricción y succión. El tama o y las áreas de inserción de los músculos en el disco abdominal sugieren que el mecanismo de succión es pasivo, o sea, sin la acción constante de los músculos.
The abdominal disc of Atelopus tadpole is a complex structure, which includes three welldefined regions with several muscles and ligaments attached to its internal surface. It is hypothesized that the disc has two mechanisms of attachment to the substrate, namely, friction and suction. The size and insertion points of the muscles and ligaments of the disc suggests that the suction mechanism works passively, without the constant action of the muscles.
