Patagonian Desert Patagonian Desert The Patagonian Desert, also known as the Patagonia Desert, Patagonian Steppe, or Magellanic Steppe, is the largest desert in Argentina and is the 8th largest desert in the world by area, occupying 673,000 square kilometers (260,000 mi). It is located primarily in Argentina with small parts in Chile and is bounded by the Andes, to its west, and the Atlantic Ocean to its east, in the region of Patagonia, southern Argentina.

Patagonian toothfish spawn in deep water (around 1,000m) during the austral winter, producing pelagic eggs and larvae. Larvae switch to a demersal habitat at
