Achatinella livida
Template:Short description Template:Speciesbox
Achatinella livida is an extinct species[1] of air-breathing land snail in the family Achatinellidae. This species was endemic to Oʻahu, Hawaiʻi.
Description
Achatinella livida shells can reach a length of 17mm and a diameter of 9.0mm, with up to six whorls.[2] Their shell is shaped like a cone with a pointed top.[2] Their shells are livid brown to purple, and the tip of the shell slowly transitions to white.[2] The shell's seam is separated by a distinct line that contains a deep orange-brown color.[2]
Distribution and habitat
Achatinella livida is endemic to the Northern Ko’olau mountains on the island of O'ahu.[3][4] Achatinella livida can be found in their native moist forest habitat on Metrosideros polymorpha ('Ohi'a lehua).[2]
Conservation status
Achatinella livida is classified as critically imperiled as of 2014 with a wild population sie estimate of at least 76 individuals.[1] Similar to most Hawaiian tree snails, there are various threats to its survival, such as habitat loss and being endangered by Euglandina rosea and other predators.[5] In 2014, the captive population of A. livida consisted of 25 individuals, including three adults.[1] This captive population was founded in 1997 with 13 adults taken from its original range.[1]
