In Costa Rica, rattlesnakes mate during the early dry season (December and January) and births occur in the early rainy season (May-July). Gestation is therefore about 6 months. The mean number of offspring is 22.9 and is significantly correlated with the size of the female. Newborn rattlesnakes are 27,543.0 cm in length and weight 11.4 - 46.3 g. They are relatively docile. Adult males are longer and heavier than females. Females seem to have their first litter when their size exceeds 120 cm. Este trabajo presenta una serie de datos sobre la biología reproductiva de esta especie y su relación con las características ecológicas del ámbito que abarca, con el fin de contribuir al conocimiento de su historia natural.
