title: [Morphologic study of the embryonic development of the Amazonian turtle Podocnemis expansa, Pelomedusidae].
abstract: Two egg groups from four clutches of the Amazon turtle, Podocnemis expansa, were incubated at 32-34 degrees C and 35-38 degrees C, respectively. The incubation of the first group lasted approximately 47 days and the second 43 days. To standardize the stages, a series of 25 stages was recorded, based on observation of morphological evolution related to incubation duration and its respective temperatures.
