30+ Interesting Blue and Black Snakes (14 are Venomous)

Snakes are diverse creatures found in almost every part of the world. Their diversity not only includes their habitats, behaviors, and venoms but also extends to their appearances. Typically their colors work as an advantage for them to predate or hide from predators themselves by camouflaging. Some snakes, however, take on breathtakingly beautiful colors and are a sight for sore eyes. Today, we’ll be talking about 30+ interesting blue and black snakes.

However, there are also some species that are naturally blue. In this article, we’ll get into details for 10 uncommon blue and black snakes and then list the rest.
