Contribuição à biologia de serpentes da Bahia, Brasil: I. vivíparas Contribution to reproductive biology of snakes in Bahia, Brazil: I. viviparous
<abstract language="eng">Great part of lhe avaiable data about snakes reprodution refers to species coming from subtropical and temperate regions. In Brazil, the data is rather rare and can be found in various works where information is restricted. Results from studies developed with five viviparous snakes - Crotalus durissus cascavella (Wagler, 1824). Bothrops erythromelas(Amaral, 1923), B. leucurus (Wagler, 1824), Helicops leopardinus (Schlegel, 1873) and Thamnodynastes strigilis (Thiinberg, 1787) - which come from the Northeast of Brazil (Bahia) are described.
