单词	Urochordata
释义	Urochordata /ˌjʊərə(ʊ)kɔːˈdeɪtə / plural noun Zoology A group of chordate animals that comprises the tunicates. Subphylum Urochordata, phylum Chordata. Although this classification is widely accepted, some authors recognize three chordate phyla: Urochordata for the urochordates, Cephalochordata for the lancelets, and Vertebrata for the vertebrates.... For this reason, the three subphyla, Urochordata, Cephalochordata, and Vertebrata, will be treated separately. Some zoologists would put the Urochordata closer to the Echinodermata, instead of within the Chordata proper. Origin Modern Latin (plural), from uro-2 'tail' + Chordata.
