Stunning photos show native Brazilians swimming underwater
These stunning photographs offer a rare glimpse into the lives of some of Brazil's most remote tribes.
Photos show the indigenous Kamaiurá people diving underwater and swimming beneath a waterfall in the Amazonian basin.
The tribe, which has a population of just over 500, lives in the Upper Xingu region around Lake Ipavu, four miles from the Kuluene River.
The Kamaiurá, whose name means 'a raised platform to keep meat, pots and pans', were first contacted by the outside world in 1884.
Its population was ravaged by disease in the 1950s but the region was declared a national park by the Brazilian authorities in 1961 to prevent the spread of deadly epidemics.
The Kamaiurá society spans a number of villages while their diet consists mainly of fish, porridge, pepper and bananas.
