North Senteel Island is unlike any other place on earth, it is home to an independent, isolated, and extremely dangerous tribe.
North Centennial is like any idyllic spot in the Indian Ocean, with many trees off a blue coast with crystal clear waters. To be murdering the fate of its visitor.
Sentinel translates to "guard", which is what the islanders do to prevent any foreign visitors from entering it, making it the most difficult place in the world to visit, the most dangerous island in the world, and the home of the world's most isolated tribes.
Sentinel Island is home to an independent tribe that refused to contact the outside world 60,000 years ago.
The people of North Centennial attacked the strangers who lost their way to their land. In 1896 they stabbed a fugitive.
In 1974, they received crew of filmmakers with arrows, and in 2004 a tribesman targeted an Indian Coast Guard helicopter sent to check for signs of survival after the earthquake.
In 2006, they killed two fishermen who accidentally fished in their waters.
Residents of North Snentenel have weapons of arrows and spears, and use fishing nets and basic rowing boats.
They hunt and eat from their catch and collect wild plants, but there is no evidence of agriculture or even ways of setting fire.
According to the 2011 census effort, and based on anthropologists' estimates of the number of people on the island, there are likely to be between 80 and 150 people on North Sentinel, although it may be as high as 500 or less than 15.
Based on one visit to the island in 1967, residents live in light shacks with sloping roofs, built against each other.
The language of the people of the island is not understood by anyone outside this place, and no one knows what the people of the island call themselves, or their view of the world.
The killing of 27-year-old American John Zhao on the island as he tried to visit last year drew the world's attention to the small islanders.
The young man was surrounded on arrival on the island after paying fishermen to take him to the island at sea, 50 kilometers west of the city of Port Blair, but he completed his way alone.
So far, the violent behavior of the island's inhabitants prevents the possibility of careful observation or information gathering, and as such, very little is known about them.
