| Research Abstract |
Based on specimens collected by our own field surveys and some published literature, we recognized 166 species of land snails to be occurred in Palau islands. Among the 166 species, 5 species was introduced, 7 were widely distributed species or indigenous species common to neighboring region, and 149 were endemic species. Endemic rate was very high(89. 7%) and approximately 60% of the endemic species were undescribed species. Some of the endemic species show extensive morphological diversity and ecological differentiation, suggesting that adaptive radiation have occurred in those groups. It is remarkable that endemic land snail fauna comprised of more than 150 species is still surviving in Palau island, while most of endemic land snails were already extinct or endangered in other area of Pacific islands.
