Fortunately, the Turtle Conservancy recently pioneered a novel technique to tattoo the shells of tortoises. We first implemented our technique on reintroduced Burmese Star Tortoises in Myanmar to great success -- two smugglers were recently caught and prosecuted in Thailand because of our tattoos. For the past 4 years we have been working with our partner, Durrell Wildlife Conservation Trust, to mark the shells of larger Ploughshare Tortoises by engraving their shells with a Dremel tool, but this could not be done on younger tortoises with thin shells. To solve this size problem, we provided Durrell with the equipment and training they needed to begin tattooing on these smaller tortoises.
