| Summary: | Objective: In the present study, the morphological features of common tortoise (Testudo graeca Linnaeus, 1758) found in the Pamukkale ruins and determined to be two-headed Siamese twins, were investigated using computed tomography. Material and Methods: The size and weight of the twin tortoise were measured and placed under care in a terrarium similar to their natural habitat. The anatomical features of the two headed Siamese twins were evaluated by three-dimensional volumetric computed tomography. Results: The Siamese twins combined from the end of the shell have 4 anterior extremities and 2 posterior extremities. Even though tortoises were conjoined, they were reacting independently, but had to move together due to their abnormal shell structures. The Siamese twins weighed 13.2 grams when they were found. They survived 47 days in the terrarium. The tomography scanning showed that that one of the twins was fused from the 7th vertebrae and the other from the 8th vertebrae. Although the internal organ structure is not clear, it has been observed that they use a shared cloaca. Conclusion: The anomalies rarely seen in reptiles can be caused by many factors, including environmental and genetic factors. |
