半索動物門(門) Hemichordata(phylum)
範圍註 ：
含櫟實蟲與翼鰓類的小門；牠們的外型似蟲，屬海生無脊椎動物，與脊索動物極親近。一般而言，半索動物被歸類為門，但某些資料將牠們與其他原索動物共同列入其他分類層級。半索動物是由希臘語中的hemi（意指「一半」）以及chorde（意指「繩索」）組合命名，「半索」一詞最初被提出是因為此類動物具有口盲囊，口盲囊為一條從口腔向前延伸至吻中的盲管，類似脊索的雛形。然而這項理論卻遭到否定，因為口盲囊與脊索在起源與功能上，幾乎毫無相似之處。除了吻之外，牠們的身體亦有一個短領，以及似蠕蟲的長軀幹。

| 英文.... | Small phylum that includes acorn worms and pterobranchs, characterized as wormlike marine invertebrates closely related to the chordates. While they are typically given phylum rank, some sources place the group at various other taxonomic levels with the other so-called protochordates. Hemichordates are so named for the Greek hemi, meaning "half," and chorde, meaning "string," thus, "half-chordate," which was first proposed because the buccal diverticulum, a tubular outgrowth from the mouth cavity forward into the proboscis, resembled a rudimentary notochord. This theory has since been rejected, however, because it has been determined that the diverticulum bears little resemblance in origin and function to the vertebrate notochord. Along with the proboscis, the body comprises a short collar, and a long, wormlike trunk. |
