Amastra spirizona is a species of land snail, a terrestrial pulmonate gastropod mollusk in the Amastridae family. [2]
The length of the shell of Amastra spirizona attains 18 mm. [3] The shell is conical in shape, opaque, and sculptured with fine ridges. [4] Within the shell is a small body with elongated eyes and a rough outer texture. [5]
Amastra spirizona is endemic to Hawaii. [1] It can be found in trees, specifically ekaha ferns ( Asplenium nidus ) and ōpuhe leaves ( Touchardia sandwicensis ) in the Waianae mountain range on the island of Oahu. [6]
Amastra spirizona has been collected by researchers from their original range in the Waianae mountains. Precisely thirty snails were captured to stop the population from further declining in 2015. [5] This species is preyed on by animals, which includes rats, cannibal snails, and chameleons, but is not considered federally or state endangered. [6] The Snail Extinction Prevention Program (SEPP) released around 1200 snails, including the amastra spirizona, out into a predator-free enclosure that they keep well-maintained. [7]
