Snakes consume a variety of items including termites, rodents, birds, frogs, small deer and other reptiles. Snakes eat their prey whole and are able to consume prey three times larger than the diameter of their head because their lower jaw can separate from the upper jaw. To keep prey from escaping, snakes have rear-facing teeth that hold their prey in their mouths.Venomous snakes inject their prey with venom, while constrictors squeeze their prey. They do not need to hunt everyday. Anacondas and pythons can survive for up to a year without food after feeding. Snakes hunt mostly at night.Snakes are found throughout the world except Antarctica, Iceland, Ireland, Greenland and New Zealand. Most snakes are found in tropical regions. Snakes are found in many habitats including in the water, forests, deserts and prairies. - See more at: http://www.npnewsportal.com/fear-of-snake/#sthash.VXHFd1E4.dpuf
