Snakes come in a huge variety of colors and patterns. While many people are familiar with common green and brown snakes, there are actually many species that display incredibly vibrant and diverse coloration. Non-venomous snakes in particular can have some of the most striking and beautiful designs. But what is objectively the most colorful of these harmless serpents?
Factors in Snake Coloration
Several elements contribute to the colors and patterns seen on different snake species. These include:
– Pigmentation – The types and amount of pigment in a snake’s scales impact its overall color. Melanin leads to black, brown, and olive tones. Red and yellow come from carotenoids and pteridines. Some pigments may be totally unique to snakes.
– Structural coloration – The microscopic structure of the scales can also influence color by refracting and scattering light. This generates iridescent and metallic sheens.
– Habitat – Snakes tend to match their environments for camouflage. Arboreal species are often green while desert snakes skew brown.
– Mimicry – Bright color patterns are sometimes used to mimic dangerous species as a defense tactic.
– Genetics – The genetic lineage of a snake determines what colors and patterns it can display.
Most Colorful Non-Venomous Snakes
Taking all these elements into account, the following are some of the most vibrantly colored and patterned harmless snake species:
Milk Snake
Milk snakes belong to the king snake family and are native to the Americas. They are extremely variable in coloration between subspecies and individuals. Patterns include bands of red, black, and yellow. Some lineages also display bright whites and oranges. This diversity earns milk snakes a spot as one of the most colorful non-venomous species.
Scarlet Kingsnake
These small, vibrantly red snakes inhabit pine forests in the southeastern United States. Their bodies are patterned with narrow black and white bands. The red pigment coupled with the contrasting bands make scarlet kingsnakes very visually striking.
Amazon Tree Boa
This South American species displays incredible iridescence in many morphs. Their scales refract light to create shifting rainbow hues. Patterns include diagonal stripes and ovals in bright greens, oranges, yellows, and whites.
Green Tree Python
Arboreal green tree pythons are native to Australia and Indonesia. Hatchlings start yellow, red, or blue. As adults, they develop strong green pigmentation with white and turquoise markings down the back. Their coiled posture shows off this coloration.
Emerald Tree Boa
Another stunning arboreal species, emerald tree boas inhabit the Amazon rainforest. Most display deep jewel tones of emerald green. However, some locales exhibit vivid orange and purple tones instead.
Rainbow Boa
Rainbow boas have a wide distribution across Central and South America. As their name suggests, they display incredible color variety. Morphs include reds, oranges, yellows, greens, and everything in between.
The King of Color: Honduran Milk Snake
Of all these vibrant snakes, the prize for most colorful likely goes to select morphs of the Honduran milk snake. Their bands contain just about every color in the rainbow. Patterns can include deep pinks, purples, oranges, yellows, greens, blues, and more. When combined together, the resulting snakes are nothing short of dazzling. For this kaleidoscope effect, the Honduran milk snake takes the crown for the most colorful non-venomous serpent.
Conclusion
Many non-venomous snakes around the world display gorgeous and vibrant coloration. Milk snakes, kingsnakes, tree boas, and tree pythons are just some examples. Factors like pigmentation, structural coloration, and genetics all contribute to their stunning combinations of colors and patterns. But the Honduran milk snake, with its unparalleled diversity of vibrant rainbow stripes and bands, emerges as the most visually spectacular of all. Its striking display of color makes the Honduran milk snake the most colorful of the harmless snakes.
