Aspectos do comportamento reprodutivo de Eunectes Murinus (Linnaeus, 1758)

Abstract

This observation analyzes reproductive habots of Eunectes murinus, viviparous snake endemic os South America, with wide distribution in Brazil. One of its most flashy characteristics consists in its giant size and marked sexual dimorphism, important adaptive advantage of the species. Although it is not considered threatened with extinction, contemplative analysis are scarce (among other reasons) due to its semi aquatics routine. Its reproductive habits involve copulation between a female individual and one or more males, wich compete for days in order to perpetuate their genes. the females often cannibalize males and neonates, probably due to the long fasting period they pass through during the breeding season Parthenogenesis was also reported in the species, highlighted by genetic evidence. In this study, social media data has been classified and analyzed from different parameters (localization, environment, time of the year, number of animals and behavior), evidencing literature findings and instigating the realization of new behavioral studies in the field or ex situ.
