中文摘要 | 纓鰓蟲(Laonome albicingillum Hsieh)為環節動物門多毛綱管棲生物;在具有豐 富生物相的臺灣淡水河口三角洲沙地,底棲生物中纓鰓蟲為優勢種。幼蟲時期為自由浮游主 活擔輪幼蟲,幼蟲發生變態後,固著(settle)於河口三角洲沙地淤泥中,形成棲菅。成熟蟲 體長約3至6公分,活體呈青色。纓鰓轟無疣足,蟲體呈圓柱狀,尾端體節逐漸縮小。剛毛反 轉(setae reverse)現象發生在體節第八節至第九節,排糞溝(fecal groove)在第八節從背面 向右翻轉至第九節腹面,體表除了排糞溝位置改燮,大剛毛(setae)與有鉤剛毛(uncini)的位 置亦對調。從胸節至腹節各部位橫切面的比較,內部器官位置沒有隨著體表剛毛翻轉,僅有 表皮細胞和外部剛毛和排糞溝的位置有轉移 |
英文摘要 | The sabellid Laonome albicingillum Hsieh is the most dominant polychaete species in a mangrove estuary in northern Taiwan. It is a tube dwelling species. The sabellin species usually has eight thoracic, numerous abdominal segments and a terminal pygidium. Mature individuals range in length from 3 to 6 cm. They are pale green. The setae reverse occurs between the 8th and 9th segment, the fecal groove turns over from the 8th dorsal side to the 9th abdominal side. The setae and uncini positions also change each orther. The comparison of inside of thoracic and abdominal segments is only the integument occurring reverse. |
