A mythical creature.

The Galapagos Land Iguana resembles the mythical creatures of the past-dragons with long tails, clawed feet and spiny crests. Land Iguanas have a spiky dorsal crest which runs along the neck and back. They are heavily bodied with thick back legs and smaller front legs.
Land Iguanas have a short blunt head and pleurodont teeth (Having the teeth attached by their sides to the inner side of the jaw, as in some lizards). Its tail is quite a bit longer than its trunk. In reality, these harmless lizards are alive today, but endangered in their own native land.
