In pictures: Lost tribe in South America

The people are painted with dyes made from fruit. The red figures are firing bows at the plane used to take the photos. They're thought to be men, and the black figure a woman.

The tribe live in these buildings with thatched roofs, called malocas. They have fires for cooking and heat - the bigger ones are used for sleeping and the smaller ones for cooking.

Around the buildings are gardens which the tribe use for growing things to eat.

There are only 100 uncontacted tribes in the whole world, and half of these are in Brazil or Peru. This tribe live in an area of the Amazon Rainforest.

The photos were taken by the Brazilian Government, to prove the tribe exists so their land, and way of life, can be protected.
