英文释义

名词 n.
  1. Any marine annelid of the genus Hyalinoecia, especially Hyalinoecia tubicola of Europe, which inhabits a transparent movable tube resembling a quill in color and texture. rare
    — The use of the tube is to protect the body from the pressure of the soft mud in which it stands immersed. When the tube is overset or cast out by the waves or accident, the worm leaves it, and becomes, in its turn, exposed to enemies. To protect itself from these while a new tube is being secreted, nature has amply furnished the Sao with a series of bristling lances on each side. These arms are of exquisite make, very fine and very sharp; and those of the upper bundle have their points bent and inclined towards those of the lower bundle, which are likewise bent to meet them.
