Abstract

The energy that lizards and snakes invest in reproduction can vary according to their life history strategies and may be reflected in the variation of the number of offspring born, their dimensions, and changes in the weight of reproductive females. We determined the reproductive effort of a female Metlapilcoatlus olmec, which gave birth to a total of 12 offspring, resulting in a 27.59 % loss of her body mass and a relative clutch mass (RCM) of 0.38. The offspring exhibited smaller body measurements compared to previous reports for this species.
