and Nicobar, the Sentinelese is one of the important tribes . Eminent anthropologists of the Indian subcontinent
, refer them in different names like Sentineli, Senteneli, Sentenelese, North Sentinel Islanders. These Sentinelese tribes have concentrated in North Sentinel Island of Andaman and Nicobar, completely detached from the happening of the outside world of modernity.
