Giant Galapagos Tortoise
The Giant Galapagos tortoise (or Chelonoidas nigra) is a species of reptile endemic to the Galapagos Islands and does not appear anywhere else in the world. They come in two types – saddleback shelled and dome shelled – and both variants have a dull grey-brown shell and scaly, grey coloured skin. Saddleback shell tortoises have long necks and live in dry lowland areas, while dome shell tortoises have short necks and live in humid highland areas.
Gharial
Gharials (or Gavialis gangeticus) are a critically endangered species of crocodile native to the rivers of the Indian subcontinent. With recent estimations stating there are just 200 left in the wild, the dwindling population is now restricted to just four stretches of river in Nepal and North India. Their collapse in numbers has been caused by the increase in river pollution reducing the amount of fish in the water, as well as by sand-mining destroying sandbanks that are essential for egg-laying females.
Aldabra Giant Tortoise
Endemic to the Seychelle Islands, an Indian Ocean archipelago east of the African coast, the Aldabra giant tortoise (or Aldabrachelys gigantea) is a reptilian species capable of growing to extremely large sizes. Males average between 200 and 250 kg, while the smaller females still average between 121 and 159kg. Their shells are a dull, grey-brown colour made up of peaked keratinous plates and their skin is scaly and grey.
