THIS live snake, approximately 3 feet in length, was discovered on the fence that protects the caimans swamp at the Zoological Park on Monday, when it was noted by a passerby.He alerted the park security, who then took a twig and pushed the snake back into some nearby trees. It created quite a stir among the persons present, while parents could be seen ushering their kids away and out of the zoo. One parent was heard talking about improper safety measures at the zoo, as children usually walk closely to the fence to view the caimans, and it was lucky that someone saw the reptile before it could have caused any trouble.
