Wilts，E.F.，Wulfken，D.，阿尔里希斯Martinez Arbizu，P. 2012. Squatinella rostrum（Milne，1886）（轮虫：Lepadellidae）的肌肉系统，通过共聚焦激光扫描显微镜显示，并提供有关其trophi和整体形态的额外新数据。动物学报（斯德哥尔摩）93：14-27。
利用光学显微镜、扫描电子显微镜和激光共聚焦显微镜对单殖体轮虫Squatinella rostrum进行了研究，以揭示其内部和外部解剖结构的新的形态学资料。总体上，可视化的躯体肌肉组织显示五对纵向肌肉（肌肉I-V）和九个环形肌肉（肌肉I-IX）。与其他物种相比，喙突猪的特征是缺乏几个纵向和环形肌肉（例如头括约肌、括约肌冠和冠状部）。乳房肌肉组织的重建显示了总数为7对和两个不成对的乳房肌肉。可能同源的躯体和mastax肌肉在其他，迄今为止调查轮虫进行了讨论。此外，我们提供了一个系统发育评价所揭示的形态特征，并建议可能的自形特征支持Squatinella和Lepadellidae。最后，我们提到了一些惊人的相似之处，在形态，生态和运动的方式Squatinella和Bryceella，这可能表明两个类群的关系更密切。

The monogonont rotifer Squatinella rostrum was investigated with light, scanning electron and confocal laser scanning microscopy to reveal new morphological data on its inner and outer anatomy. In total, the visualized somatic musculature displays five paired longitudinal muscles (musculi longitudinales I–V) and nine circular muscles (musculi circulares I–IX). Compared to other species, S. rostrum is characterized by the absence of several longitudinal and circular muscles (e.g. musculus longitudinalis capitis, corona sphincter and pars coronalis). A reconstruction of the mastax musculature revealed a total number of seven paired and two unpaired mastax muscles. Possibly homologous somatic and mastax muscles in other, thus far investigated rotifers are discussed. Moreover, we provide a phylogenetic evaluation of the revealed morphological characters and suggest possible autapomorphic characters supporting Squatinella and Lepadellidae. Finally, we refer to some striking similarities in the morphology, ecology and way of movement of Squatinella and Bryceella that may indicate a closer relationship of both taxa.
