Cool. Thanks for the links, Tyler. It seems that scientists have been observing them from afar and also learned things from semi-modernized Andamanese as well as from past contact before the most remote people cut off contact. This is particularly fascinating:
"Initially thought to have been badly affected by the tsunami on Christmas 2004, it was soon revealed that the islanders had moved to higher ground before disaster struck – almost as if they knew the giant tidal wave was coming. "
http://www.apisrilankan.com/world/last-known-isolated-tribeIt has been reported that some wild animals sense tsunamis, hurricanes and earthquakes before they strike. I wonder if these wild people share some ability with these other wild creatures?
I also found these reports:
"All we know is that the Sentinelese are hunter-gatherers; they do not farm. They live on fruits, fish, tubers, wild pigs, lizards and honey."
http://www.odditycentral.com/travel/north-sentinel-island-the-worlds-hardest-place-to-visit-2.html"Life continues day to day, tending fires from past lightning strikes, hunting wild pig, gathering fruits, tubers, fish, crabs, honey, grubs and the eggs of turtles and seagulls."
http://old.himalmag.com/component/content/article/280-The-Sentinelese-of-the-Andamans.html"They hunt pig and turtle and fish with bows and arrows in the coral-fringed reefs for crabs and fish, including striped catfish-eel and the toothed pony fish. They also gather fruits, wild roots, tubers and honey."
http://www.survivalinternational.org/tribes/jarawa"They live in groups of about 40 to 50 people, in a hunter gatherer lifestyle, eating berries, pig, monitor lizard, fish and other wild foods."
https://mathildasanthropologyblog.wordpress.com/2008/04/08/the-jarawa-onge-and-sentinelese-of-the-andaman-islands"They gather and eat the vegetation that surrounds them, e.g., berries, tubers, plants, coconuts and other fruits, and wild pigs"
https://prezi.com/5fbfqbtxp8qo/the-sentinelese-people"The ocean is a very important source of food for these secluded islanders. They utilize a variety of “home-made” spears, harpoons, nets, and dugout canoes to aid them in their quest for dinner. As a whole, the Sentinelese appear to be a healthy and thriving community which is in part due to their good diet (which includes seafood, honey, plants, seeds, and coconuts). Another contributing factor may be their healthy and active sex lives which was documented by Indian Anthropologists during a “contact” expedition in the 19070?s."
http://www.seathos.org/tag/sentinelese-people/"The Jarawa ... get their food from the surrounding forest and sea. Their food items include Wild boar, big monitor lizard, crab, fish, sea curdle, eggs and molluscs like trouchus, turbo and bivalves. Wild jackfruit, a small fruit (tale), tubers like potato (anima) and arum (cheuba), are also eaten. The Jarawas relish honey (lauba). Meat is roasted or boiled, fish and molluscs boiled. They neither add salt nor sugar to their food. The Jarawa are totally unaware of alcoholic drinks or any narcotic." - G. K. Ghosh, Tourism Perspective in Andaman and Nicobar Islands, 1998, p. 65,

This is about the last survivor of another group of traditional Andamanese people called the Bo (
http://en.wikipedia.org/wiki/Bo_people_%28Andaman%29):
"Boa was born in the jungle of the northern Andamans and grew up in traditional society, learning to gather wild potatoes and hunt for wild pigs, turtles and fish."
