Definition of Prosobranchia in English: Prosobranchiaplural nounˌprɒsə(ʊ)ˈbraŋkɪəˌpräsəˈbraNGkēə Zoology A group of molluscs which includes the limpets, abalones, and many terrestrial and aquatic snails. They all have a shell, and many have an operculum. 〔动〕前鳃亚纲软体动物 Subclass Prosobranchia, class Gastropoda Example sentencesExamples - Gastropods were traditionally classified into three main subclasses, Prosobranchia, Pulmonata, and Opisthobranchia.
- He therefore placed the bellerophontids in the ‘Prosobranchia’.
- In the traditional classification system, the class Gastropoda has been divided into three subclasses, Prosobranchia, Pulmonata, and Opisthobranchia.
- They share certain basic characteristics with the Prosobranchia, but they are placed with the Opisthobranchia because there is a smoother transition from the Cephalaspidea to the other opisthobranch orders.
Derivativesnoun ˈprɒsəbraŋk Zoology A symposium on prosobranch phylogeny was held in 1986 which resulted in several papers using cladistic analysis to produce phylogenetic hypotheses of various gastropod groups. Example sentencesExamples - Pulmonates are dioecious and hermaphroditic as are prosobranchs, but pulmonates develop directly (there is no larval form).
- Traditionally, opisthobranchs have been recognized as a natural group and have been included within the gastropods together with prosobranchs and pulmonates.
- All three of these investigators have worked extensively with the marine prosobranch, C. californica.
- Serotonergic neurons arise early in gangliogenesis in pulmonate, prosobranch, and opisthobranch embryos.
