The term 'Amazon Menaces' refers to two species of snakes found in the Amazon rainforest: Boas and Panhas. Boas are large, non-venomous snakes that can grow up to 13 feet in length and are found throughout the Americas. Panhas are smaller, venomous snakes that can reach up to 5 feet in length and are found in South America. Both species are considered a threat to humans and other animals due to their aggressive behavior and potential to cause injury or death.
