Achatina fulica – is a species of land snail in the family Achatinidae, known commonly as the giant African snail. This is one of the largest snails but is considered the most invasive.
BEWARE: This snail eats about 500 species of vegetation unlike our native Australian snails that DO NOT eat plants [or your garden]. If you see this overseas-and they are as close as Papua New Guinea, then do not bring them home. If you see them here in Australia, contact Biosecurity Australia immediately.
