Iguana Species Identifier

What is the Iguana Species Identifier?

The Iguana Species Identifier identifies likely species or morph of iguanas 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.

Iguanas generally live 15-20 years when they are well looked after. Diet-wise they are a herbivore, which shapes almost every feeding decision you make. Green iguanas reach 1.5m and need a custom enclosure the size of a small room, not a vivarium. They are strict herbivores, need intense UVB, and adult males can become genuinely dangerous during breeding season. The usual suspects for this species are metabolic bone disease, kidney failure from protein-rich diets, tail and toe loss from poor shedding, so any noticeable change is worth following up.

How does the Iguana Species Identifier work?

The result is based on matching the traits you describe against commonly documented characteristics for iguanas, not genetic testing. Individual iguanas vary more than averages suggest, so read the number as a reference point rather than a measurement.

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 Iguana Species Identifier?

1. Pick your adult size (Very small, Small, Medium, ...)
2. Pick your coat length (Hairless or very short, Short and dense, Medium, ...)
3. Pick your ear carriage (Erect, Folded or dropped, Semi-erect, ...)
4. Pick your overall build (Slender and fine-boned, Balanced, Stocky and heavy-boned)
5. Pick your dominant color pattern (Solid single color, Two-tone or bicolour, Brindle, merle, tabby or ticked, ...)
6. Press Calculate, then read the result alongside the sources listed below

If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this

This calculation assumes a healthy adult iguana with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
