  • Abstract This study investigates the distribution in species composition and abundance of pteropods in relation to temperature, salinity, and water masses in the waters of southern Taiwan from February 2004 to October 2005. In total, 25 pteropod species belonging to 13 genera and 6 families were recognized. The mean abundance of pteropods in the study area was 77.3 ± 32.3 ind. / 100m3. 
    The five most dominant species were Limacina inflata, Creseis virgula var. conica, C. acicula, L. bulimoides, and L. trochiformis, and together they contributed 81.0% of the total number of pteropods, among them, L. inflata occupied 46.7% and was the most dominant species in all seasons. In general , the composition of dominant species of pteropods in each season were similar but ranked different in abundance. 
    The abundance and species number of pteropods changed seasonally. The abundance of pteropods was higher in 2004 than in 2005, and higher in summer than in winter. The species number was lower in autumn(9 ± 1) and higher in summer(13 ± 1). The abundance and the species diversity of pteropods were generally higher in the western site(the northern South China Sea) than in the eastern site(Kuroshio Current).
    In the waters of southern Taiwan, the abundance and diversity index of pteropods and the abundance of the five most dominant species showed no significant correlation with the sea surface temperature and salinity, except the species number that was negatively correlated with salinity.
