Galapagos Tortoise at the Auckland Zoo (New Zealand)
Galapagos tortoises live on a group of islands called the Galapagos off the west coast of South America. These huge animals are threatened in the wild by fire and introduced predators such as feral dogs and pigs. They evolved with no need for speed, as the Galapagos Islands have no native predators for the tortoises. A full-grown Galapagos tortoise can weigh 260kg, so it takes five Zoo staff to lift one tortoise.
