单词 Rotifera
释义

Definition of Rotifera in English:

Rotifera

plural noun rəʊˈtɪf(ə)rərōˈtifərə
Zoology
  • A small phylum of minute multicellular aquatic animals which have a characteristic wheel-like ciliated organ used in swimming and feeding.

    〔动〕轮虫;轮虫动物门

    Example sentencesExamples
    • Because the new taxon lacks syncytia, a key character for the Rotifera and Acanthocephala, the Micrognathozoa cannot be included in Syndermata.
    • The remaining members of this novel metazoan clade were Rotifera, Acanthocephala (together Syndermata), and Cycliophora.
    • Micrognathozoa lack this characteristic feature and, therefore, are postulated to be more basal in the Gnathifera, as a sister-group either to Gnathostomulida or Rotifera / Acanthocephala.
    • Substantial phylogenetic evidence from both morphology and molecular data indicates that acanthocephalans have a close evolutionary relationship with Rotifera.
    • Evolutionary relationships within the phylum Rotifera are poorly understood despite the important role that they play in freshwater ecosystems.

Origin

Modern Latin (plural), from Latin rota 'wheel' + ferre 'to bear'.
