Finding kingsnakes in New Mexico can be difficult!

Here’s why:

Regardless, these non-venomous, mostly docile snakes are fascinating. For example, did you know that kingsnakes EAT venomous snakes? Believe it or not, it’s true!

Today, you’re going to learn about the 6 types of kingsnakes in New Mexico!

Identifying Characteristics:

  • Adults are typically 36 to 48 inches in length.
