栖息在太平洋高岛的Partula属陆生蜗牛为研究物种的起源和分化提供了极好的机会：法属波利尼西亚的Moorea特有类群已经得到了很好的研究。为了控制农业害虫非洲大蜗牛Achatina fulica的数量，一种食肉蜗牛Euglandina rosea被引入了Moorea。它以每年1.2公里的速度在全岛蔓延，消灭了地方性的帕图拉。一个物种在野外已经灭绝;并且推断Ezigltmdina的传播速度，预计所有剩余的分类群（可能除了甜菜夜蛾）将被消灭。
Land snails of the genus Partula, inhabiting the high islands of the Pacific Ocean, have provided exceptional opportunities for studies oil the origin and differentiation ofspecies: The endemic taxa ofMoorea, in French Polynesia, have been particularly well studied. In an attempt to control the numbers of the giant African snail, Achatina fulica, which is an agricultural pest, a carnivorous snail, Euglandina rosea; has been introduced into Moorea. It is spreading across the island at the rate ofabout 1.2 km per year, eliminating the endemic Partula. One species is aiready extinct in the wild ; and extrapolating the rate of spread of Ezigltmdina , it is expected that all the remaining taxa (possibly excepting P. exigua) will be eliminated by
