The Bo was one of the ten Indigenous tribes of the Great Andamanese people, originally living on the western coast of North Andaman Island in the Indian Ocean.
[2] There are still a handful of people who identify themselves as members of the tribe living on a reservation on Strait Island, but none can speak the original language.
[5] Census takers were told that an epidemic had come from the neighboring Kari and Kora tribes, and the Bo had resorted to killing all of their own who showed symptoms.
[4] In 1949, any remaining Bo was relocated, with all other surviving Great Andamanese, to a reservation on Bluff Island.
The last speaker of the Bo language, a woman named Boa Sr, died at age 85 in late January 2010.
