Last survivor of unknown Amazon tribe missing after attack - NatGeo News Watch

Last survivor of unknown Amazon tribe missing after attack - NatGeo News Watch: "the sole survivor of the unknown tribe was known to dig holes as deep as 15 feet. At the bottom of the holes spikes as long as two feet have been found, suggesting this is how he catches prey. A big hole has also been found in his house (in the picture above), which he might use as a place to hide, she said.

What makes the Brazilian authorities think the Man of the Hole may be alive? 'There is evidence that he has been picking the fruits and digging up the manioc he planted,' Watson said.

FUNAI officials had been checking on the Man of the Hole every few weeks, Watson said. 'Now they are organizing a more permanent watch over him.'"
