The Islands of Tuvalu consist of six atolls and reef islands. The smallest, Niulakita, was uninhabited until it was settled by people from Niutao in 1949.
Funafuti is the capital of Tuvalu. It is a true atoll that consists of 30 islands, or motu, as called by the Tuvaluans, surrounding a lagoon 20 kilometres north to south by 11 kilometres east to west.
