World's Rarest Tortoises race against extinction at Singapore Zoo
Singapore, May 2016 – Boosting Singapore Zoo’s efforts to save the world’s most threatened vertebrates from extinction is its newest exhibit—Tortoise Shell-ter. Guests at the park can now look forward to learning more about some of the world’s rarest tortoises and ongoing efforts to increase their dwindling numbers.
Tortoise Shell-ter showcases three critically endangered tortoise species—the Ploughshare Tortoise, Radiated Tortoise and Burmese Star Tortoise—making it one of Singapore Zoo’s exhibits with greater conservation and educational values. Other threatened species at the new attraction include the Elongated Tortoise and the Yellow-footed Tortoise. The naturalistic exhibits feature rock walls, habitat specific planting, and climate-controlled micro-habitats, including special lighting, heating with temperature gradient and humidity control, to create the ideal home away from home for these delicate species to thrive.

Some of these tortoises share their homes with other compatible reptiles, such as the Rock Monitor, Black and White Tegu, Green Iguana and Veiled Chameleon. This provides inter-species interaction, which is a great form of enrichment for the inhabitants, as well as providing a more interesting viewing experience to the guests.
In addition to featuring threatened species, Tortoise Shell-ter is also a sanctuary for some former-victims of the illegal wildlife trade, which have been confiscated and sent to Singapore Zoo, such as the Indian Star Tortoise.
In the wild, these land-dwelling reptiles’ shells (called carapaces) shield them against predators but they are no match for the combination of habitat loss and human exploitation, including unsustainable consumption and poaching for the illegal pet trade.
Aside from showcasing these chelonians at the Tortoise Shell-ter, Singapore Zoo also contributes to safeguarding the future of other threatened species of turtles through conservation breeding and the maintenance of assurance colonies. The latter refers to the safekeeping of endangered species populations under human care in case something happens to the already diminished numbers in the wild.
Great care was taken in designing Singapore Zoo’s Tortoise Shell-ter, now home to some of the world’s most threatened tortoises such as the critically endangered Ploughshare Tortoise (pictured above).Only 200 mature specimens are left in the wild, and survive in a 12 square km patch in Madagascar. Their decline in recent years is a result of poaching for the illegal pet trade. The species is at extreme risk of extinction in the wild within 10-15 years.

Singapore Zoo has a good track record of breeding threatened chelonian species, both terrestrial (tortoises) and aquatic (turtles and terrapins) and has recently had the first hatching for the critically endangered Painted Terrapin. Other threatened species bred at the Zoo include the endangered Elongated Tortoise and Burmese Mountain Tortoise and the critically endangered Southern River Terrapin.
The park’s breeding programmes offer the possibility of reintroducing the animals to the wild whenever their safety can be ensured in their natural habitat. In addition, Wildlife Reserves Singapore (WRS) actively supports on-site and off-site breeding and reintroduction programmes in a few Southeast Asian countries. It also collaborates with trade monitoring organisations to raise awareness on illegal wildlife trade of tortoises.
Dr Cheng Wen-Haur, Deputy Chief Executive Officer and Chief Life Sciences Officer, WRS, said: “Within the span of just one human generation, many turtle and tortoise species have been decimated to near extinction through our activities. We are working in the zoo as well as in their native habitats to prevent these ancient creatures from disappearing from earth altogether. Through the Tortoise Shell-ter we would like to highlight their plights to our guests and to engage them to join us in our effort to save the species.”
