, 2002 缘毛类纤毛虫属纤毛门、寡膜纲,是一类营自由生活或寄生生活的单细胞真核生物.该类群物种繁多,仅我国就有11科34属约450种之多;其分布广泛,生境复杂高度多样化.因此,对缘毛类开展系统的深入研究,不仅在理论上,而且在实践上特别是关于自然环境的保护和利用方面,都具有十分重要的意义.但是 ...

, 1993 描述了寄生在团头鲂(Megalobrama amblycephala)鳃上的一吸管虫新种,双泡毛管虫。活体无色透明至淡黄色,正面观为卵圆形至长椭圆形,稍扁平;侧面观为棒状或香肠状,常附着在鳃小片上。身体的表膜中有不明显的细小颗粒。吸管指状,一束,着生在虫体前端,一般有4—8根,最多达23根,收缩时其表面出现明显的螺旋纹8—11个。两个伸缩泡,交替地进行伸缩,彼此间隔约为10μm,位于吸管基部的胞质中。大核短杆状或椭圆形,核膜明显,染色质均匀。小核圆球形。成虫和幼虫没有固着柄,

, 2002 Corliss在1968年将缘毛类纤毛虫提升为亚纲,作为寡膜纲四大组成类群之一(另三个亚纲分别为膜口亚纲、咽膜亚纲和盾纤亚纲)。现有游动目(Mobilida)和固着目(Sessilida),其中固着目包括12科30属,是水体中常见的自由生活纤毛虫种类。其形态特征是身体由口纤毛区(oral ciliary field)、反口区(aboral pole)和轮状带(telotrochal band)三部分组成。然而缘毛类纤毛虫有着丰富的形态多样性:有单体和群体之分,有无柄和有柄之别 ...
