If you keep savannah monitors, avoid letting males live together. Mature males also possess ossified structures, known as hemibaculainside their hemipenes. This technique is widely used to determine the gender of snakes and a few lizard species accurately, but it is not always effective with monitor lizards.
A potential bonus of this procedure is that your vet may notice early signs of internal disease, which he can then treat, allowing you to avoid future health problems.
Before establishing housing arrangements for your pets, confirm all of your lizards' genders with a veterinarian or breeder. A savannah monitor breeder or herpetological veterinarian should be able to initially demonstrate the procedure for you. Further complicating matters, females may evert their hemiclitori, which can be difficult to distinguish from hemipenes.
Most female monitors possess analogous organs of indeterminate function, called hemiclitori. Identifying the hemipenes is usually pretty simple in youthful specimens but not so in mature lizards, who typically get irritated with touching and examination. To do so, your vet will make a small incision in the monitor's belly, inflate the cavity with air, and visualize either ovaries or testes.
Some keepers attempt to evert their lizard's sex organs by applying pressure to the base of the tail. The turf-oriented actions of the males aren't the only behavioral differences that exist between male and female savannah monitors. Show Comments. From there, smoothly push your index finger and thumb over the tail moving in the direction of the back limbs.
