Tantilla

Tantilla are small snakes, rarely exceeding 20 cm (8 inches) in total length (including tail). They are generally varying shades of brown, red or black in color. Some species have a brown body with a black head.

Tantilla are nocturnal, secretive snakes. They spend most of their time buried in the moist leaf litter of semi-forested regions or under rocks and debris.

The diet of snakes of the genus Tantilla consists primarily of invertebrates, including scorpions, centipedes, spiders, and various insects.
