Amastra micans, commonly known as the Amastrid land snail, is a species of land snail, a terrestrial pulmonate gastropod mollusk in the family Amastridae. [ 2 ] [ 3 ] [ 4 ] It is a critically endangered species and endemic to the Hawaiian Islands , mainly found in the Waianae Mountains of Oahu .
Since these snails reproduce slowly and only exist in a few limited locations, they are very vulnerable to threats. Habitat destruction for agriculture and invasive species are noted as the biggest reason for population decline, though fires, collecting, drought, hurricanes, logging and human recreation are also to blame.
Known as Achatinella fuscobasis, the snail species had dwindled to only 11 individuals in the wild by 1991, according to officials with the Department of Land and Natural Resources in Hawaii ...
A herd of axis deer in Maui. Hawaii is the most isolated major land mass in the world and that isolation has led to very high rates of endemism.Uniquely adapted endemic species are often sensitive to competition from invasive species and Hawaii has had numerous extinctions (List of extinct animals of the Hawaiian Islands).
Achatinella apexfulva is a (probably) extinct species of colorful, tropical, arboreal pulmonate land snail in the family Achatinellidae, once present on Oahu, Hawaii. A. apexfulva is the type species of the genus Achatinella. The specific name, apexfulva, meaning "yellow-tipped", refers
Succinea caduca is one of the few land snail species on Hawai'i that is nonendangered, as well as inhabiting multiple islands. [5] A possible explanation for this is its distribution in dry areas, which may only partially overlap with the distribution of Euglandina rosea, a predator snail species that was introduced to Hawai'i and is a major contributor to native Hawaiian land snail species ...
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.
