As its name indicates, the Giant Zanzibar Land Snail is native to the east African territory of Zanzibar.
The shell can grow to some 15cm long and 7 cm diameter.
Like other Giant African Land Snails, it is hermaphrodite and eats plant-derived material.
(Another Giant Land Snail, the Reticulated, Lissachatina/Achatina reticulata, is also native to Zanzibar.)
