There are untouched and endangered tribes in the beautiful Andamans. Entering the tribal reserves, meeting or photographing the tribals is prohibited and against the law. Please refrain if anyone offers you a trip to meet the tribal people. Adhere to the law and respect the Andamanese tribes.
However, you should visit the Anthropological Museum in Port Blair to have a look at their tools, weapons, and photographs showing their lives and traditions.
There are two groups of the indigenous tribes—The Shompen and Nicobarese of Mongoloid descent living in the Nicobar Islands and the Onge, Sentinelese, Jarawa and Andamanese of Negroid descent living on the Andaman Islands.
Still living in isolation on the North Sentinel Island, the Sentinelese is the least studied tribe. They are nearly 250 in number. They are not clothed as they have been living in total isolation for many centuries. Adornments of bark and shell, like necklaces, arm bands, waist bands, etc. are used by the Jarawa.
