Avaliação seminal na falsa coral Oxyrhopus guibei

Abstract

The suborder of the snakes is composed of a variety of species that can present different reproductive aspects among themselves, occurring variations correlated to the environment in which they live and the season of the year. To know the real reproductive status of an animal must be taken into account the macro and microscopic morphological study combined with techniques such as histology to analyze minute structures and their functions. False coral (Oxyrhopus guibei) is a sinanthropic and non- venomous animal common in the metropolitan region of São Paulo state and has a continuous reproductive cycle. This project described the sperm cycle in males of Oxyrhopus guibei throughout the year, showing peaks of sperm production between winter and spring. Semen collection occurred monthly in the animals kept in the laboratory of Ecology and Evolution Laboratory (LEEV) of the Butantan Institute.
