前言据1977年Fauchald报导,现已发现的多毛类缨鳃蚕科有290种,其中45种分布在北美西海岸(Hartman, 1969; Banse, 1972,1979),它们多数栖息在浮动船坞下周丛生物间、岩岸和潮下带的贝壳、卵石及软泥等底质中.从数量上看,它们在很多区域中是底栖群落的优势种(Kendal,1979; Bell,1982).虽然缨鳃虫科种数多而分布普遍,但我们仅掌握了很零星的有关它们生殖和发育的知识.有关其幼虫发育的详细报告有:wilson(1936)的Megalomma(=Branchiomma) vesicuIosum,1946年奥田四郎(Okuda,S.)的potamilla myriops和Chone echaudata (=teres), Forsman(1956)的Manayunkia aestuarina
Foreword According to a 1977 report by Fauchald, 290 species of polychaete have been found, 45 of which are found on the west coast of North America (Hartman, 1969; Banse, 1972, 1979). Most of them inhabit the floating dock next week Among the sediments of seashells, pebbles and slimes in rocky and subtidal zones, they are dominant species of benthic communities in many areas (Kendal, 1979; Bell, 1982) However, we have only a very sparse knowledge of their reproductive and developmentalities. More detailed reports on their larval development include: Megalomma (= Branchiomma) vesicu Iosum by Wilson (1936), Okuda Shiro (1946) (Okuda, S. potamilla myriops and Chone echaudata (= teres), Forsman (1956) Manayunkia aestuarina
