The identification of Favella ehrenbergii, a marine planktonic ciliate, has largely been based on its lorica features. This approach is potentially problematic given the polymorphic lorica during this organism's life cycle. We isolated a population of F. ehrenbergii from the coastal waters of Incheon, Korea, and revealed its infraciliature using the protargol staining method. Phylogenetic analysis based on small subunit rRNA gene sequences was also performed. Results showed that this population possessed 16 collar membranelles (CM) and about 100 somatic kineties. These features are highly conserved, even in later dividers. As such, the number of CM and somatic kineties can be used as key characteristics for identification of Favella species.
海洋浮游纤毛虫Favella ehrenbergii 的鉴定主要基于其刺丝囊的特征。鉴于该生物在生命周期中刺丝囊存在多态性，这种方法可能存在问题。我们从韩国仁川的沿海水域分离出了一个 F. ehrenbergii 种群，并使用蛋白银染色法揭示了其纤毛结构。还进行了基于小亚基 rRNA 基因序列的系统发育分析。结果表明，该种群具有 16 个领膜纤毛（CM）和约 100 个体毛线。这些特征非常保守，即使在后期分裂中也是如此。因此，CM 的数量和体毛线可以用作鉴定 Favella 物种的关键特征。
