There’s a noticeable size difference between the two, the indigo snake is larger and more dominant. The average adult Eastern Indigo Snake measures 60-82 inches in length. These huge and heavy snakes are glossy black with iridescent violet or blue accents when viewed in the sunshine. The golden-yellow rat snake is attempting to make a run for it when the indigo snake makes the first attack. Having none of it, the rat snake continues to leave when the indigo snake sneakily lunges from behind and starts swallowing his opponent head-first. Eastern Indigo Snakes devour a variety of vertebrates that are tiny enough for them to dominate and consume. These snakes seem to prefer eating other reptiles (particularly poisonous snakes), although they have also been observed eating frogs, mammals, and fowl. For a moment, the rat snake has its nose and mouth hanging out of the side of the Indigo snake’s grasp. With both of their bodies slithering today, it isn’t long until the Indigo snake begins swallowing. These serpents are not constrictors, thus they grip their food in their jaws. They do this by holding it against the earth and gnawing it until it stops resisting. They will also swallow prey whole. You can watch as the body of the rat snake gets shorter and shorter as it fills the belly of the Indigo snake. It takes less than three minutes before the beautiful black and iridescent creature is finished with his meal. He slithers away back towards a rocky cavern to have an afternoon nap after such a large lunch! One thing’s for sure – it’s a good day not to be a rat snake!
