Oithona similis belongs to the Copepoda Cyclopoida. It is highly abundant throughout many parts of the world ocean and supposed to be a cosmopolitan species. Aim of this project is to find out whether O. similis, a key species in the three chosen study areas (Arctic, Antarctic and North Sea), is indeed a cosmopolitan species. A further goal is a better understanding of its life cycle (or in case there are cryptic species of their life cycles) including feeding habits and generation times of the developmental stages, as well as the combined role of food resources and temperature within its/their life cycle/s. The literature is full of contradictory information on all aspects of the biology of O. similis. The main goal will be to find the reasons for these contradictions, whether they are caused by the great biological and/or genetical flexibility of the species or by the fact that there are several cryptic species. Such species may be very stenoecious as indicated by their similar or even identical morphology. This will be studied by using genetical and morphological techniques. The results will then dictate the further procedure. In case of a cosmopolitan species it will be examined whether morphologically different populations exist within each of the three study areas. In the other case it will be differentiated between the single cryptic species.

Oithona similis 属于桡足纲 Cyclopoida。它在世界海洋的许多地方都非常丰富，被认为是一个世界性物种。该项目的目的是查明三个选定研究区域（北极、南极和北海）的关键物种 O. similis 是否确实是一个世界性物种。进一步的目标是更好地了解其生命周期（或者在其生命周期中存在神秘物种的情况下），包括摄食习惯和发育阶段的世代时间，以及其/它们的食物资源和温度的综合作用。生命周期/秒。文献中充满了关于 O. similis 生物学各个方面的相互矛盾的信息。主要目标是找到这些矛盾的原因，无论它们是由物种的巨大生物学和/或遗传灵活性引起的，还是由存在多个神秘物种的事实引起的。这些物种可能非常狭窄，如它们相似甚至相同的形态所示。这将通过使用遗传和形态学技术来研究。结果将决定进一步的程序。对于世界性物种，将检查三个研究区域内是否存在形态不同的种群。在另一种情况下，它将在单个神秘物种之间进行区分。
