Shaped like an exuberant sea horse standing on its head, Mayotte is the most southerly and oldest of the Comoros islands, with relatively low, rounded hills and a prominent circling coral reef. A collective Territory of France, its inhabitants are EC citizens. This "island" actually consists of three main islands: Grande Terre, Petite Terre, and the rock of Dzaoudzi, and is a remarkable natural environment filled with birds, lemurs and numerous species of flora and other fauna.
