The Îles Crozet are a group of sub-Antarctic islands located in the southern Indian Ocean. They are part of the French Southern and Antarctic Lands and consist of several islands, with Île de la Possession being the largest. The islands are known for their rugged terrain, diverse wildlife, and unique ecosystems. These islands are uninhabited except for a small research station operated by France. The Îles Crozet are home to various species of seabirds, including king penguins and albatrosses, making them an important site for ecological research and conservation efforts.
