Flatworms are intriguing subjects for systematic and evolutionary studies because they are ecologically and phylogenetically diverse parasites, some of which cause serious disease in humans and in the animals we grow and harvest as food globally. A systematic revision of the ?fish blood flukes? (Digenea: Aporocotylidae) will underpin the development of a comprehensive and robust phylogeny that tests hypotheses about geographic distribution, coevolution of flatworms and their vertebrate hosts, and the origin of complex life cycles in digenean flatworms. In addition, as a basal blood fluke lineage, resolving phylogenetic relationships of aporocotylids may help further reveal the evolutionary origins of tetrapod blood flukes.This three-year revisionary systematics project will produce the first global classification system for the fish blood flukes. Aporocotylids comprise emerging, significant aquaculture disease agents among the marine, estuarine, and freshwater fishes they infect worldwide. Fish blood flukes are the aquatic counterpart and close relative to schistosomes that parasitize birds and mammals, including those causing schistosomiasis in 20 million people. This project unites researchers from the US and Australia while simultaneously training two PhD students and several undergraduates in flatworm (phylum Platyhelminthes) taxonomy and systematics.

扁虫是系统和进化研究的有趣课题，因为它们是生态和系统发育上多样化的寄生虫，其中一些会导致人类和我们在全球种植和收获作为食物的动物产生严重疾病。对“鱼血吸虫”的系统修订（双殖纲：Aporocotylidae）将支持全面而稳健的系统发育学的发展，以测试有关地理分布、扁虫及其脊椎动物宿主的共同进化以及双殖纲扁虫复杂生命周期起源的假设。此外，作为基础血吸虫谱系，解决孔子叶纲的系统发育关系可能有助于进一步揭示四足动物血吸虫的进化起源。这个为期三年的系统学修订项目将产生第一个鱼类血吸虫的全球分类系统。阿孔子叶类是它们在全世界范围内感染的海洋、河口和淡水鱼类中新出现的重要水产养殖病原。鱼血吸虫是水生血吸虫的对应物，与寄生于鸟类和哺乳动物的血吸虫密切相关，其中包括导致 2000 万人患血吸虫病的血吸虫。该项目联合了来自美国和澳大利亚的研究人员，同时对两名博士生和几名本科生进行扁虫（扁形动物门）分类学和系统学方面的培训。
