The green anaconda is one of the largest snakes in the world, native to the swamps and rivers of South America. It can grow up to 30 feet long and weigh over 500 pounds, making it a powerful predator. This snake primarily hunts aquatic animals, including fish, birds, and mammals. Green anacondas are non-venomous constrictors, meaning they kill their prey by wrapping around it and squeezing until it suffocates. They are excellent swimmers and spend much of their time in water, using their camouflage to blend in with their surroundings.
