对枝角类科、属和当地动物群内的分类群数量的估计表明，只有约129种(占所有已知物种的17%)可被认为是充分描述的(有效种)，而约146种被认为是描述得相当好的(可用种)，但需要用现代调查方法进行进一步的研究。所有其他种类的地位都是模糊的，对水母属、水蚤属(包括水蚤属)、巨型水母属(Megafenestra)、片尾水蚤属(Scapholeberis)、裸腹水母属(Eurycercus)、水母属(Chydorus)、眼泡水母属(EphEmeropus)和侧耳属(Pleuroxus)的比较研究最好。已知的有效物种数量最多的是欧洲、北美、澳大利亚和南美洲，最少的是非洲。大量模糊的枝角类物种的存在对大陆水域的动物学、动物地理学和生态学研究产生了负面影响。
An estimation of the number of taxa within families, genera and local faunas of Cladocera reveals that only c. 129 species (17% of all known species) may be considered as sufficiently well described (valid species), and c. 146 as rather well described (fair species) but needing further study using modern methods of investigation. The status of all other species is vague;The families Chydoridae, Daphniidae and Sididae and genera Diaphanosoma, Daphnia, (including Daphniopsis), Megafenestra, Scapholeberis, Eurycercus, Chydorus, Ephemeroporus and Pleuroxus have been comparatively studied best. The largest number of valid species is known from Europe, North America, Australia and South America, and the smallest number from Africa. Presence of large number of vague species of Cladocera negatively affects faunistic, zoogeographic, and ecological studies of continental waters.
