What is the Snake Species Identifier?
The Snake Species Identifier identifies likely species or morph of snakes from pattern and color cues. Knowing what you're working with shapes everything from diet and housing to expected size and temperament. That is useful for new owners and shelters alike.
A well-cared-for snake usually lives somewhere between 15 and 25 years. As a carnivore, what a snake needs from its diet changes across its life stages. Snake requirements vary enormously by species, from a 1m colubrid to a 5m constrictor. All need a thermal gradient, secure hides at both ends, and a lid that genuinely locks, since almost every escape traces back to a loose enclosure. The usual suspects for this species are respiratory infection, retained shed and stuck eye caps, scale rot, so any noticeable change is worth following up.

How does the Snake Species Identifier work?
The result is based on matching the traits you describe against commonly documented characteristics for snakes, not genetic testing. Treat the result as a well-founded estimate. Every snake is an individual, and your vet's judgement outranks any online tool.
What affects the result
- Physical traits such as size: coloring and markings
- Behavioral traits: which can be just as informative as appearance for some questions
- Age: since juvenile traits can differ noticeably from adult ones
- Photo or description quality: the more specific your input, the more useful the match
How do you use the Snake Species Identifier?
- Pick your adult size (Very small, Small, Medium, ...)
- Pick your coat length (Hairless or very short, Short and dense, Medium, ...)
- Pick your ear carriage (Erect, Folded or dropped, Semi-erect, ...)
- Pick your overall build (Slender and fine-boned, Balanced, Stocky and heavy-boned)
- Pick your dominant color pattern (Solid single color, Two-tone or bicolour, Brindle, merle, tabby or ticked, ...)
- Press Calculate, then read the result alongside the sources listed below
If two people care for your snake, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Two snakes with identical numbers on paper can still need different care. Breed or line, body condition, activity level and any existing health conditions all pull the real answer away from the average. If your snake has a diagnosed condition, is pregnant, or is very young or very old, treat the figure here as the loosest of guides and let your vet set the actual target.
