[edit] Description
The Texas Night Snake grows from 10 to 16 inches (25 to 40 cm) in length. It is typically a light grey or tan in color, with dark brown or dark grey blotching down the back and an unmarked underside. They have smooth scales, eyes with vertically elliptical pupils, and are considered to be rear-fanged venomous, though they are not dangerous to humans.
[edit] Behavior
As their common name implies, they are a primarily nocturnal snake. Their diet consists of primarily lizards, but they will also eat smaller snakes and occasionally soft bodied insects. They prefer semi-arid habitats with rocky soils. They are an oviparous species that breed in the spring rainy season, laying 4-6 eggs that take approximately 8 weeks to incubate before hatching.
[edit] Geographic range
The Texas Night Snake ranges from southern Kansas to southern Colorado, and south throughout New Mexico, the western half of Texas to central Mexico.
