How to Tell a Boy Lizard From Girl

1. Look at the cloaca. The cloaca is the opening near the base of the tail where waste products are excreted. In male lizards, the cloaca is usually larger and more prominent than in female lizards.

2. Look at the coloration. In many species of lizards, males are more brightly colored than females. This coloration is used to attract mates.

3. Look at the size. In many species of lizards, males are larger than females. This is due to the fact that males need to be larger in order to compete for mates.

4. Look at the behavior. Male lizards are often more aggressive than female lizards. This aggression is used to defend their territory and attract mates.

If you are still unsure whether a lizard is male or female, you can take it to a veterinarian or herpetologist for identification.
