I am a graduate student in evolutionary genetics, and I am interested in focusing my research on the evolutionary relationships between tegu species, particularly with regards to placement of blue tegus within the species T. merianae or in a species all its own. I will be searching for samples in South American collections, but would also like to see if tegu owners might be interested in sending me shed skins for DNA analysis. All owners will remain anonymous in this study, and I will gladly pay for shipping should anybody want to send samples of red, blue, black and white, or gold tegu sheds. Thank you for reading, and please let me know if you're interested!
