摘　　要：石鳖是舟山海域岩礁质潮间带常见的软体动物.由于其总体分布密度不高且经济价值低,相关形态等生物学研究及报道也甚为稀少.该文根据近几年在舟山海域采集到的8种石鳖标本,对其形态特征进行比较研究,予以补充描述,制作了分类检索表;并对其中4种常见种类的壳板进行了解剖,对比其壳板缝合片具有的齿裂数,发现与历史文献描述有一定差异.上述结果可为后续石鳖的研究提供基础资料.Chiton is a common species in the rocky intertidal zone of the Zhoushan sea area.The biological research about morphology on the chiton is insufficient as its population density and the economic value are not high.In this study,the morphological characteristics of 8 chiton species collected in the Zhoushan sea area in recent years were compared and described supplementally,and a classification key was made.The shell plates of four common species were dissected,and the slit numbers of shell plate sutural lamina showed some differences compared with discription in previous literature.The above results will provide basic data for the future research of chitons.
