THE FORMATION OF THE CALCAREOUS HABITAT TUBE BY HYOROIDES EZOENSIS OKUDA (SERPULIDAE, POLYCHAETA)
Abstract:
Hydroides ezoensis Okuda, a kind of serpulidae, is distributed extensively in NorthChina sea water. The radioactive tracer isotope calcium and High-speed autoradiography(HSARG) with liquid emulsion film of labelled section are being tested, the procedureincludes immersion of the emulsion coated specimen slides in a scintillator (PPO-POPOP-dioxane) & exposure for a few hours at -30℃ followed by development and fixation. The present experimental data show that 45Ca is mainly distributed in epithelium tissues situated at head-throax (peristomium), antennal crown and collar, but the radioactive calcium has never been detected by HSARG within the so-called calcium-secreting glands which previous workers named. A pair of glands secreted only some of organic material under our experiment and observation, radioactive calcium cation was not detected by HSARG procedure. So these secre-tingglands may be better named as the tube organic secreting-glands rather than the calcium-secreting glands in Hydroides.
