Can you tell the age of an iguana by the size of its dorsal spines?

It is a common myth that the age of an iguana can be determined by the size of its dorsal spines. However, there is no scientific evidence to support this claim. In fact, dorsal spine size can vary greatly within the same species and even within the same population. Therefore, it is impossible to accurately determine the age of an iguana simply by looking at the size of its dorsal spines.

The best way to determine the age of an iguana is by examining its physical characteristics, such as its size, weight, and coloration, and by considering its history and behavior. For example, younger iguanas tend to have brighter colors and smoother skin, while older iguanas may have larger jowls and more pronounced dewlaps.

It is important to note that iguanas can live for up to 20 years or more in captivity, so proper care and nutrition are crucial to ensuring their long-term health and well-being.

No, you cannot tell the age of an iguana by the size of its dorsal spines. The size of an iguana's dorsal spines is determined by a number of factors, including its diet, health, and genetics. Even if you could tell the age of an iguana by the size of its dorsal spines, it would not be an accurate way to determine its age, as there is a great deal of variation in the size of dorsal spines among iguanas of the same age.

The best way to determine the age of an iguana is to take it to a veterinarian who specializes in reptiles. The veterinarian will be able to examine the iguana and give you an accurate estimate of its age.
