Partulina redfieldi is a species of tropical air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinellidae.
Partulina redfieldi appears in various colors, [2] and the shells are found to be polymorphic, exhibiting a wide range of white to brown shades with varying numbers of white or brown bands. [3] Partulina redfieldi must reach 3 to 5 years of age before it can reproduce and are only capable of producing up to 5 babies every year. [3] The snail has a juvenile mortality rate of 42%. [4]
Partulina redfieldi are endemic to the island of Molokai, Hawaii. This species is commonly found on the smooth leaves of the ‘ohi’a lehua tree or metrosideros polymorpha, also endemic to the Hawaiian Islands. [3]
From 1983 to 1995, the general population of Partulina redfieldi grew significantly from 100% to 900%. [3] Since 1995, the population has decreased by 85%, due to rat predation, which has shown itself to be a growing threat to tree snail species endemic to Hawaii. [5] Partulina redfieldi population initially decreased by 85% within just 2 years of being discovered by rats. [6]
Achatinella apexfulva is an 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 to the yellow tip of the snail's shell. Inspired from the taxon, the species has been given common names such as yellow-tipped Oʻahu tree snail or Hawaiian yellow-tipped tree snail. Officially, it is listed as ‘critically endangered’ by the IUCN, however, this is because its conservation status has not been updated in 28 years.
Achatinella fulgens is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc within the Achatinella genus of the family Achatinellidae. The species is one of a collection of snail species commonly referred to as Oʻahu tree snails or pupu kuahiwi in the Hawaiian language.
