Atlantisia is the smallest flightless bird in the world. It lives only on Inaccessible Island in the Atlantic Ocean and belongs to the rail family.
Atlantisia differs from other rails by its complete lack of flight and the smallest size among flightless birds. It is important for the island's nature as an endemic and a participant in the food chain.
