The Zanzibar Channel is a strait in south-eastern Africa, separating the island of Unguja (also known as Zanzibar) from mainland Tanzania. The channel is 120 km long and 30-40 km wide, with depth varying from a few dozen metres (in the centre) to a few hundred metres to the north and to the south. In ancient times the overall depth of the channel has been considerably smaller (about 120 m less during the last ice age).
