Meaning
This flag stands for the French Southern and Antarctic Lands, a French overseas territory made up of remote islands in the southern Indian Ocean such as Kerguelen and Crozet.
There is no permanent population, only scientists and support staff, so the emoji shows up in research news, wildlife documentaries about penguins, albatrosses and seals, and geography quizzes, with 🐧 or 🧊. “Documentary night: penguins of the Crozet islands 🇹🇫🐧”
