Check Out These Ssseriously Cool Ground Snake Facts

One of the interesting ground snake facts is that its head is barely broader than its neck and body.

Ground snakes are a collection of 14 snake species in the genus Sonora, all endemic to North America. There are also ground snakes endemic to South America that belong to the genus Atractus. Of all these ground snakes, the most noteworthy is the western ground snake (Sonora semiannulata), which is also the type species for the Sonora genus of ground snakes. The western ground snake species is hence known as the common ground snake and sometimes as the variable ground snake. The ground snake gets its name because it dwells underneath the ground during most of the day and comes out at nightfall and if there is rain to feed on a diet of scorpions, centipedes, and other animals. The variable ground snakes can be colored differently and they breed indiscriminately with snakes colored differently than themselves. The western ground snakes (Sonora semiannulata) are famously non-poisonous and are harmless to humans. The western ground snake is a Least Concern snake species according to its IUCN status.
