I was looking at the fairly recent news of the arrival of the Malagasy big headed turtle (Erymnochelys madagascariensis) at Jersey zoo in the UK which is now the only place outside of Madagascar to hold this species. Freshwater turtles are an incredibly threatened group of reptiles for many reasons and are therefore kept ex-situ by many zoos for captive breeding / insurance populations. This gives us zoochatters the chance to view these animals in all their strange beauty even as their populations are being decimated in the wild. I was thinking it might be interesting to create a thread solely on this topic and listing the zoos around the world where some of these rare turtles that are in such peril in the wild can be seen in captivity. What vulnerable, endangered or critically endangered freshwater turtles do you know of being kept by zoos ?
