Brumation is a phrase scientists use to describe animals that tuck themselves in for the winter and as spring temperatures warm up these animals begin to wake up. Zookeepers can also maintain special warm climates when necessary. Flick, technically Heterodon platirhinos is also known as a Hog Nosed Snake and in recent cold months has been engaged in ‘brumation’. Unlike true hibernation, bromating snakes are not asleep: they’re alert and less active, lowering the heart rate down to as little as 5% , plus shutting down the digestive system, including the liver and kidneys yet still maintaining most of their previous weight. These snakes have specialized venom glands and their saliva can seep into wounded prey. When alarmed, these snakes can roll over and “play dead”.
