title: Differences in sterol composition of gonads of the lottiid limpets Nipponacmea concinna and Nipponacmea fuscoviridis from northeastern Japan.
abstract: This is the first report on the sterol composition in Nipponacmea concinna and Nipponacmea fuscoviridis, 2 dominant species of lottiid limpets. There were significant differences in sterol composition between male and female gonads of the limpets. Previous studies have shown that zymostenol and zymosterol are major lipid components of male gonads of the nacellid limpets Cellana grata and Cellana toreuma. In contrast, in this study, only trace amounts of zymosterol were detected in male gonads of N. fuscoviridis.
