Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in area to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Geologically, the continents largely correspond to areas of continental crust that are found on the continental plates. However, some areas of continental crust are regions covered with water not usually included in the list of continents. Zealandia is one such area (see submerged continents below). Islands are frequently grouped with
Smallest organisms chameleons ("B. minima"), 14–19 millimetres for male Mount d'Ambre leaf chameleons ("B. tuberculata") and 15–16 millimetres for male "B. micra", though females are larger. Of the aforementioned geckos, "S. ariasae" was first described in 2001 by the biologists Blair Hedges and Richard Thomas. This dwarf gecko is endangered and lives in Jaragua National Park in the Dominican Republic and on Beata Island ("Isla Beata"), off the southern coast of Hispaniola in the Dominican Republic. The world's smallest turtle is the speckled padloper tortoise ("Homopus signatus") from South Africa. The males measure , while females measure up to almost . The
