What is the Leopard Gecko Species Identifier?
The Leopard Gecko Species Identifier identifies likely species or morph of leopard geckos 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.
Leopard geckos generally live 15-20 years when they are well looked after. Diet-wise they are an insectivore, which shapes almost every feeding decision you make. A single adult needs at least a 90x45cm floor area with a warm hide around 32C, a cool hide, and a humid hide to help shedding. Belly heat from a mat with a thermostat matters more than overhead heat. Keep an eye out for metabolic bone disease, retained shed on toes and eyes, impaction from loose substrate. These are the conditions leopard geckos are most commonly seen for.

How does the Leopard Gecko Species Identifier work?
The result is based on matching the traits you describe against commonly documented characteristics for leopard geckos, not genetic testing. The math is only as good as what you feed it, so an accurate, recent input matters more than the formula itself.
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 Leopard Gecko 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
Worth doing: jot down the date and the result each time. A single number tells you little, but a trend across a few months tells you a lot about your leopard gecko.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for leopard geckos, but your leopard gecko may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
