Famous Oahu Tree Snails are going extinct unless Briefkaart

All the 39 species of Oahu tree snails, snails belonging to the genus Achatinella, have been made extinct or are on the endangered list. These snails are endemic to the island of Oahu in Hawaii. Disturbances in the ecosystem caused due to human activities are responsible for the large-scale exision of these snails. Collection by humans for extracting their shells, predation pressures, loss of habitat, low growth rate, and low fertility rate, have led to a rapid decline in snail populaties. Species introduced to the island by humans, either toevalally or intentionally, like the carnivorous snail Euglandina rosea and several species of rotanden, which feed on these snails, is the biggest threat to their survival.
