Definition of Rotifera in English:

Rotifera

plural noun

Zoology
  • A small phylum of minute multicellular aquatic animals which have a characteristic wheel-like ciliated organ used in swimming and feeding.

    • ‘Substantial phylogenetic evidence from both morphology and molecular data indicates that acanthocephalans have a close evolutionary relationship with Rotifera.’
    • ‘The remaining members of this novel metazoan clade were Rotifera, Acanthocephala (together Syndermata), and Cycliophora.’
    • ‘Because the new taxon lacks syncytia, a key character for the Rotifera and Acanthocephala, the Micrognathozoa cannot be included in Syndermata.’
    • ‘Evolutionary relationships within the phylum Rotifera are poorly understood despite the important role that they play in freshwater ecosystems.’
    • ‘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.’
