My wife spent part of her childhood on a farm near Cinco Lagos. She saw lots of poisonous snakes, including an especially aggressive type called the urutu that a farmworker dispatched with a machetes. Years later, she still knew her snakes. We decided one day to have lunch with our friend Sylvie at a German restaurant that was also in Cinco Lagos. The last stretch of the way to the restaurant was a narrow dirt road bordered by rain forest on both sides. Suddenly, Monica exclaimed, “Look. An urutu!” Sure enough, a huge one slithered across the shoulder of the road and disappeared into the brush. The urutu pitviper (bothrops alternatus) is a venomous species found in Brazil, Uruguay, Paraguay, Argentina. They are thick snakes that can reportedly exceed two meters in length. The color pattern is variable, from brown to tan to grey to slightly olive. The bite causes severe local tissue damage and can be fatal.
