全世界已知的大型腕足动物约有500种，是原始甲壳类动物中相对较小的一组。除了少数例外，它们生活在临时的水生系统中，在干旱和半干旱地区最为丰富。由于许多地区尚未开发，特别是蛤虾和蝌蚪虾的物种数量由于难以识别而被低估，物种清单将随着未来的调查而增加。鳃足类是单系的，但序数间的关系，以及在较低的分类水平上的许多进化关系仍然不清楚。正在进行的分子研究将更准确地描述物种多样性和系统发育模式。除了一些无肢目科，大部分科并不局限于北方或南半球或特定的动物地理区域。大型鳃足类动物被用于评估临时湿地的质量和功能。由于临时湿地的数量和质量下降，一些物种变得濒临灭绝，并被世界自然保护联盟列入红色名录。
With about 500 known species worldwide, the large brachiopods are a relatively small group of primitive crustaceans. With few exceptions they live in temporary aquatic systems that are most abundant in arid and semi arid areas. As many regions remain unexplored and as especially the number of species in clam shrimps and tadpole shrimps is underestimated due to difficult identification, the species list will increase with future surveys. The Branchiopoda are monophyletic, but inter-ordinal relationships, as well as many evolutionary relationships at lower taxonomic levels are still unclear. Ongoing molecular studies will more accurately depict species diversity and phylogenetic patterns. With the exception of some anostracan families, most families are not restricted to the northern or southern hemisphere or specific zoogeographical regions. Large branchiopods are used for the assessment of the quality and function of temporary wetlands. Due to the reduction in number and quality of temporary wetlands, several species became endangered and are red listed by the IUCN.
