Guatos
From NativeWiki
The Guatos were a tribe of South American Indians of the upper Paraguay. They are of a European fairness and wear beards.
They live almost entirely in canoes, building rough shelters in the swamps. They aided the Brazilians in the war with Paraguay 1865-70. Less than two dozen Guatos survive today.
Recently a poetic documentary about the Guato was released: 500 Souls.
