This is a live image of the bdelloid rotifer Philodina roseola. Bdelloid rotifers are microscopic freshwater invertebrates best known for their capacity to undergo frequent cycles of desiccation and rehydration, their long-term asexuality, which is manifested in the absence of males and meiosis, and the ability to capture foreign genetic material at levels unprecedented in metazoans. This image of an adult female emphasizes characteristic structures such as the ciliary ring, or corona, the pharynx with a mastax consisting of hard jaws (trophi), a set of circular and longitudinal muscles, bilateral ovaries with oocyte nuclei, and the parthenogenetically developing egg. The birefringence picture was taken with new video enhanced polychromatic polscope. An eye or camera can directly see the colored polarization image in real time through the ocular with brightness corresponding to retardance and color corresponding to the slow axis azimuth. Image size is 400x240 micron

本数据集呈现了一幅活体水生微型无脊椎动物、轮虫科成员Philodina roseola的实时图像。轮虫科成员以其能够频繁经历脱水与复水周期、长期的无性生殖能力（表现为雄性个体及减数分裂的缺失）以及捕捉外来遗传物质的能力——这在多细胞生物中极为罕见——而著称。本图像聚焦于成年的雌性个体，并着重展示了其特征性结构，如纤毛环（或称冠）、具有硬颚（或称颚须）的咽部、一套环形和纵向肌肉、两侧的卵巢及其中的卵母细胞核，以及通过无性生殖方式发育的卵子。该图像采用新型的视频增强多色偏振光显微镜拍摄，实现了实时观察。通过目镜，观察者可直接看到彩色偏振图像，其中亮度与延迟率相对应，颜色则与慢轴方位角相关。图像尺寸为400x240微米。
