Lt Governor of Andaman and Nicobar Ram Kapse said the Mongoloid tribes on Nicobar island Nicobarese, Shompens and Holschu had not suffered any casualties.

The 100-odd Onges tribe and 250-odd Jarawas also did not suffer casualty, he added.

All of 400-strong Shompen tribe in Shompen Island are safe, Vice Admiral A K Singh, director general of coast guard said, adding, the pilot of an Indian Coast Guard helicopter sighted the Sentenalese in an island.

Helicopter and boats carrying relief supplies reached these tribes after the tsunami.

Campbell Island is near the Indonesian island of Sumatra, the epicentre of the massive 9.0 magnitude quake that rolled across much of South and South East Asia but the dense mangrove forest has saved the Shompens from the onslaught of tidal waves, scientists said.

Most of these aborigine groups are highly endangered human races in the world and serve as the surviving links between modern and primitive civilisations, Executive Director of Anthro-pological Survey of India Ajay Bagchi said.
