Snakes form a key link in the food chain. They act as predators, and as prey. They help maintain a healthy ecosystem and environment. Snakes use their highly-developed senses of sight, taste, hearing and touch to locate, recognize and track their prey. Some snakes use a lethal dose of venom, modified saliva, to paralyse and kill their prey while others use their powerful muscular bodies to squeeze their prey to death. Below is a list of snakes found in Akagera National Park.
