A THREE-LEGGED ploughshare tortoise seized from illegal smugglers in Hong Kong has been given a new home at Chester Zoo, after experts fitted it with a unique set of modifications to help it get around.
The tortoise – one of the world’s rarest animals with fewer than 300 remaining in the wild – was rescued by customs officials from a would-be wildlife trader who was found with a suitcase concealing 57 live and endangered tortoises when travelling from the Comoro Islands off the coast of East Africa in 2019.
The illegal trafficker was subsequently jailed for two years, the heaviest penalty ever imposed under Hong Kong’s animal protection laws at the time.
The ploughshare tortoise (Astrochelys yniphora) was immediately transferred into the care of conservationists at Kadoorie Farm and Botanic Garden Wild Animal Rescue Centre in Hong Kong, where it was found to be missing its front left leg, as well as claws on its hind left leg, possibly due to a birth defect or injury picked up when very young.
Experts therefore set about fitting three support rollers under its lower shell, or plastron, to help it to walk and balance.
Now, the plucky male tortoise has arrived at Chester Zoo where vets have since made further modifications to the wheels to ensure his mobility support is perfectly optimised to help him get around his new surroundings.
Conservationists at the zoo have affectionately nicknamed the tortoise Hope and say he’ll eventually join an important European conservation-breeding programme, which is playing a vital role in saving the critically endangered species from extinction.
Dr Gerardo Garcia, Curator of Lower Vertebrates and Invertebrates at Chester Zoo, said: “Hope is an incredibly special tortoise, for many reasons.
“Firstly, ploughshare tortoises are exceptionally rare. It’s not just the world’s most threatened species of tortoise, it’s one of the most threatened animals on the planet, full stop.
"Fewer than 300 now remain in the wild, mostly due to their overexploitation by illegal wildlife traders – leaving them functionally extinct in their home of Madagascar.
“In addition Hope has a remarkable life story, having been rescued from smugglers, discovered to have a missing leg and then having a prosthetic mobility support specially fitted to help him get around. It works wonderfully well - he moves even quicker than his three neighbours. He’s settling in nicely to his new home and hopefully, in several years’ time once he’s more developed, he’ll go on to produce offspring and contribute to the survival of the species thanks to the vital insurance population in conservation zoos.”
In the wild, the ploughshare tortoise is found only on a small, remote stretch of sand, rock and bamboo on the island of Madagascar.
The species is listed under the highest protection category of the Convention on International Trade in Endangered Species (CITIES), prohibiting all forms of international commercial trade. It is listed as critically endangered by the International Union for the Conservation of Nature (IUCN) having been poached to the very brink of extinction.
Just 63 ploughshare tortoises exist legally outside of Madagascar, as part of vital conservation breeding programmes battling to save the species. Chester Zoo is now home to four of these.
With relatively little known about the species, scientists at the zoo are now using 24-hour CCTV cameras to monitor the tortoises and analyse their behaviour.
Kat Finch, a Conservation Scientist at the zoo, said: “Our special cameras are enabling us to get an around-the-clock insight into the behaviour of the tortoises for the very first time.
“We’re looking not just at the group as a whole but at the individuals within it too. Interestingly, we’re seeing there are significant differences in behaviour between them, and we believe this has never been documented before.
“Ploughshare tortoises are so, so rare and it’s vitally important that we learn as much detailed information about them as we possibly can. This data may help us to further improve their care and ensure we’re providing the best possible conditions to help them thrive.
"Ultimately, we hope that by closely studying them in this way, we’ll unlock information that will optimise chances of successful breeding. With so few ploughshare tortoises remaining on the planet, every single birth could be absolutely crucial to their survival.”
Highly prized for their distinctive gold and black shells, they fetch exceptionally high prices on the illegal, international black market - a result of their ever increasing rarity.
The illegal wildlife trade is worth £14 billion a year and is the fourth largest international crime after drugs, arms and human trafficking.
Mike Jordan, Director of Animals and Plants at Chester Zoo, added: “This is a species that’s sadly under huge pressure for its survival and there’s a very real possibility that this species could be lost forever. That’s why Hope is such an important addition to the zoo. We refuse to sit back and see this incredible species disappear and so our aim now is to maintain an ark population, by coming together with some of the world’s other leading conservation zoos to breed a genetically viable safety net population and prevent its extinction.”
