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.
The tribe spoke a distinctive Bo language, closely related to the other Great Andamanese languages. The native name for the language was Aka-Bo ( Aka- being a prefix for "tongue"); and this name is often used for the tribe itself. They were mostly forest-dwellers (eremtaga) with a smaller number of shore-dwellers (aryoto).[1] They are a designated Scheduled Tribe.[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.[3]
