Abstract
We report on basic natural history and life history data of the Grijalva gambusia Heterophallus milleri (Poeciliidae) from a small creek in Tabasco, southern México. Basic biology of H. milleri is similar to that of other members of the tribe Gambusiini. Insects make up at least part of H. milleri’s diet, the tertiary sex ratio was female-skewed, female H. milleri produced small offspring, one clutch at a time, relied predominantly on yolk for embryo provisioning (MI: 0.73), and male size was normally distributed.
