I have one that next to nobody has heard about. The Andiperla Willinki, also known as the Patagonian Dragon, is a small insect that lives on Patagonian glaciers.
The insect is coloured brownish-red and black. It has the amazing ability to survive in extreme cold temperatures, making it one of the most fascinating extremophiles on the planet.
It was first discovered by Willink Aubert, a French explorer. Because of its rarity, small size, and extreme habitat, it was thought to be extinct for quite some time. It was, however, rediscovered in 2001 on the Torres del Paine glacier by a film crew.
