How does sexual dimorphism manifest regarding size in *Bothrops jararaca* and *B. alternatus*?
Answer
Females are larger and heavier than males in both species.
Sexual dimorphism is a consistent feature observed across both *Bothrops jararaca* and *Bothrops alternatus*. In terms of overall size, the female specimens of both species tend to grow larger and attain greater overall mass compared to their male counterparts. This pattern suggests evolutionary pressure favoring larger females, perhaps related to reproductive capacity or energy storage needs, even as the species vary greatly in their average adult lengths and preferred body configurations (slender versus stout).
