Sentineli, North Sentinel Island, Andaman Islands, Bay Of Bengal, Indian Ocean

For catching large fish, a harpoon is used which is similar in design to the fishing arrows, but nearly 2.5 m (8 ft) long. Knives are also known, but it is unclear to what extent the Sentinelese fashion them themselves.
Known tools include adzes, pounding and smithing stones, and various finely or coarsely woven baskets for small-grained or larger goods, as well as bamboo and wooden containers. Fires are maintained as embers inside dwellings, possibly assisted by resin torches. There exist fishing nets and basic outrigger canoes used for fishing and collecting shellfish from the lagoon but not for open-sea excursions.
Food consists primarily of plants gathered in the forest, coconuts, which are frequently found on the beaches as flotsam, pigs, and, presumably, other wildlife (which apart from sea turtles is limited to some smaller birds and invertebrates). Wild honey is known to be collected and the Sentinelese use a kind of rake to pull down branches to gather fruit or nuts, such as sapodilla and pandanus.
