Interesting Facts:

Texas indigo snakes use the burrows of small mammals such as prairie dogs and armadillos for their dens.

When threatened, the Texas indigo snake will flatten its head, hiss and vibrate its tail. Despite this impressive display, indigo snakes are not venomous.

Indigo snakes will attack and eat rattlesnakes. A unique adaptation that allows them to do this is their resistance to rattlesnake venom.
