厦门港三叶坚固水母的寄生生活史研究
Life cycle of parasitic species of Pegantha triloba From Xiamen Harbour
Abstract
本文对厦门港寄生于半球美螅水母宿主上的三叶坚固水母的生活史进行了研究。描述了该种寄生水母各期幼体的形态特征、发育过程、附着方式和营养来源等，并讨论了寄生在不同宿主上的发育方式、寄生在同种桔主上不同种类各期幼体特征。阐明了筐水母与其它水母的亲缘关系。 The life cycle of parasitic species of Pegatha trileho Haeckel, 1879(host: Clytia hemi sphaerica ) were studied in Xiamen Harbour.The results showed thal the morphorlogical fea-ture, developmental process, attachmental mode and nutrient ingestion in the pields were discribed for each larval stage.The developmental mode and types of the life cycles of Pegatha triloba an1ong the different host and the same host were discussed.The relationshipbetween Narcomedusa and other Hydromedusa were elucidlated.
