A newly hatched snail is called a neonate. When the giant African land snail hatches, it's shell is about 5 to 5.5 mm long, consisting of 2.5 whorls. As the snail grows, its shell extends either clockwise (dextral) or counter-clockwise (sinistral), coiling and creating whirls as the snail ages. Dextral growth is most common. [citation needed]
The shells of these snails often grow to a length of 18 centimetres (7.1 in) with a diameter of 9 centimetres (3.5 in). Certain examples have been surveyed in the wild at 30×15 cm, making them the largest extant land snail species known. [5] [6] Similar to other giant land snails such as L. fulica, A. achatina are herbivores. Their diets ...

The shells of Amphidromus are relatively large, from 25 mm (0.98 in) to 75 mm (3.0 in) in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs ...
Adults are large (shell roughly 10–15 cm long by 5 cm wide, body up to 17 cm) with a distinct reticulated (ridged) shell that is the species' namesake. Shell colouring varies with brown, orange, and yellow streaks and tends to occur in roughly vertical banding. There is also dark speckling present, more visible in the lighter streaks.
