چکیده

We report on basic natural history, life history, and diet of Priapella chamulae (Poeciliidae) from Arroyo Tres, a small creek in Tabasco, southern México. The tertiary (adult) sex ratio was heavily female-skewed, female P. chamulae produced medium-sized offspring (~2.3 mg), one clutch at a time (i.e., showed no superfetation), and relied predominantly on yolk for embryo provisioning (Matrotrophy Index: 0.71). Furthermore, P. chamulae at Arroyo Tres had relatively short guts, were highly carnivorous, and preyed mainly on terrestrial arthropods (especially ants).
