Studies on the embryo and larval development of Polydora latispinosa |
| |
Abstract: | 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. |
