Amastra micans, commonly known as the Amastrid land snail, is a species of land snail, a terrestrial pulmonate gastropod mollusk in the family Amastridae.[1][2][3] It is a critically endangered species and endemic to the Hawaiian Islands, mainly found in the Waianae Mountains of Oahu.[3][4]

Description

Amastra micans is tiny to medium-sized, with their shell measuring an average of 15mm in height and 9mm in width.[5] The shell is elongated and conical in shape, coiled in a dextral (right-handed) spiral with a pointed apex. Their shell's surface is smooth and polished, with a wide range of colors and patterns, typically light brown to dark brown, with a white or cream-colored apex.[4][5]

Amastra micans feed on waste.[4]

Distribution and habitat

This species is endemic to the Hawaiian islands, being only found on the island of Oahu. They are particularly located in the Waianae Mountains.[3][4]

Amastra micans inhabit leaves and trees, notably the leaf litter of the native tree Pipturus albidus.[5]

Conservation status

Amastra micans is classified as critically imperiled and faces various threats to its survival, including habitat loss and predation.[3][4] However, they have been relocated to a protected habitat and now only live in the central Waianae range, following extensive efforts with the Hawaii State Division of Forestry and Wildlife and Bishop Museum.[4]
