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]

Amastra subsoror was a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae. It was endemic to Maui, Hawaii. It was described by George W. Tryon and Henry A. Pilsbry in their 1911 Manual of Conchology, and was last observed in 1946. It is thought to have gone extinct due to the introduction of predators to its habitat, the destruction of its habitat, and overcollecting.

A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
Levantina is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Helicinae of the family Helicidae, the typical snails.
