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主题，因为它们是生态和遗传多样性的寄生虫，其中一些在人类和我们种植和收获的动物中引起严重疾病。系统地修订《？鱼血吸虫（Digenea：Aporocotylidae）将支持一个全面和强大的进化史的发展，测试有关地理分布的假设，扁形虫及其脊椎动物宿主的共同进化，以及在digenean扁形虫复杂的生命周期的起源。此外，作为一个基底血吸虫谱系，解决无孔虫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。这个为期三年的修订系统学项目将产生第一个全球性的鱼类血吸虫分类系统。Aporocotylids包括新兴的，重要的水产养殖疾病的病原体之间的海洋，河口，淡水鱼类，他们感染世界各地。鱼血吸虫是水生生物，与寄生在鸟类和哺乳动物身上的寄生虫有密切关系，包括那些导致2000万人血吸虫病的寄生虫。该项目联合了来自美国和澳大利亚的研究人员，同时培训了两名博士生和几名本科生在扁虫（扁形动物门）分类学和系统学。
