Txemã, the primary cacique of the Matis tribe (left) and expedition participant.  Txemã was a young man when the Matis first made contact with the outside world.  He speaks no Spanish or Portuguese, only using his native language.  Shortly before this photograph was taken, Txemã led a successful occupation of the local FUNAI station, thereby ousting the corrupt FUNAI head from his post.  With the help of astute indigenous leaders such as Txemã, the face of the Brazilian Goverment's FUNAI is slowly changing to one more indigenous.
