The Murik Lakes area a cluster of salt and freshwater lakes where the Sepik River meets the Bismark sea, in the lower Sepik River Region of Papua New Guinea. There are five villages at Murik Lakes which are situated on the coast, southeast of the regional capital of Wewak. The lakes are an intertidal environment with lagoons and mangrove swamps, and sandbanks between fresh water and the sea. Dozens of types of freshwater and saltwater fish inhabit the waters.
What sets the Murik Lake apart from anywhere else in PNG is the tradition of siblings competing for the 'elder brother' or Sana position. Remarkably, women as well as men vie for chieftainships, as these titles are never inherited automatically by the first-born male.
