Amphidromus inversus is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae. This species is particularly interesting for its arboreal (tree-dwelling) nature and the variability in its shell, which can be quite colorful and patterned. Amphidromus inversus is known for its sinistral (left-coiled) shell, which is relatively unusual among snail species as most have dextral (right-coiled) shells. The shell is elongate and often vividly colored with combinations of yellow, green, red, and white, which can vary significantly between individuals.

Other Information
Venomous?
Amphidromus inversus is not venomous or poisonous. Like most terrestrial snails, it is harmless and poses no threat to humans in terms of venom or poison.
A Danger to Humans?
There is no danger to humans from Amphidromus inversus. These snails are completely harmless and are often appreciated for their aesthetic appeal rather than feared for any potential threat.
Population Status
Specific data on the population size of Amphidromus inversus can vary depending on their habitat and region. Being a tree-dwelling species, it may face threats from habitat destruction and changes in the ecosystem. However, detailed population studies are lacking.

Life Span:
The lifespan of land snails like Amphidromus inversus can vary based on environmental conditions and predation, but many can live for several years, possibly up to a decade under optimal conditions.
Weight and Length:
The size of Amphidromus inversus can vary, but their shells typically range from medium to relatively large for land snails, with some reaching lengths of several centimeters.
Distribution:
Amphidromus inversus is found in Southeast Asia, particularly in areas like Indonesia. They are arboreal, living primarily in trees, which is somewhat atypical for land snails.
Habits and Lifestyle:
Being arboreal, Amphidromus inversus spends much of its life on trees. It is adapted to climbing and often feeds on the surface of leaves and bark. It is mostly active during the night or after rain, which are optimal times for maintaining the moisture levels these snails require.
Diet and Nutrition:
The diet of Amphidromus inversus primarily includes algae, fruit, and lichen found on the surfaces of tree bark and leaves. They may also occasionally consume dead organic material or even the bark of trees.
Mating Habits:
Like many snails, Amphidromus inversus is hermaphroditic, meaning each individual possesses both male and female reproductive organs. Mating involves both partners exchanging sperm, which they then use to fertilize their eggs. The mating process can be quite prolonged and often involves complex courtship behaviors.
