后刺才女虫胚胎及幼虫发育过程研究

应用显微技术观察了后刺才女虫（Polydora latispinosa）胚胎的发育过程及各发育阶段幼虫形态结构特点，以期为多毛类的发育生物学研究和分类学积累更多的资料。结果显示，后刺才女虫在魁蚶内表面形成瘤状突起，在外套膜上钻孔，导致外套膜溃疡发红。后刺才女虫受精卵在卵袋中发育至三刚节幼虫时，幼虫破袋而出开始营浮游生活...

Studies on the embryo and larval development of Polydora latispinosa

The embryo and laval development of Polydora latispinosa inhabiting Anadara uropygimelana was observed by microscopy and described briefly. The purpose of the study was to accumulate more material for polychaeta's developmental biology research and the taxonomy. P. latispinosa perforated the inner surface of the shell and induced the bivalve to secrete a pearly blister over the perforation. The eggs of P. latispinosa are laid in egg capsules which were attached by thin stalks to the inner wall of the female burrow. The larvae were released at a stage with three segments and lead a long planktonic life. Then each young Polydora had collected debris and formed a tube.
