Approximately 130 individuals of Acanthobdella peledina and 100 individuals of Paracanthobdella livanowi were studied. Morphometric measurements were taken to explore the body form. The digestive and the reproductive systems of leech-like annelids were analyzed for the first time in such a high number of specimens. Observation of A. peledina and P. livanowi revealed crucial differences in the reproductive system of the analyzed taxa, mostly regarding variation in the shape of the testisacs and the length of the ovisacs. The results of a digestive system analysis suggest that blood-sucking parasites of the order Acanthobdellida may also lead a predatory lifestyle. The presented findings support the taxonomic division of the order Acanthobdellida into the families Acanthobdellidae and Paracanthobdellidae. Multiple similarities between Acanthobdellida and Hirudinida were also discussed.
对约130只佩氏棘蛭个体和100只利氏副棘蛭个体进行了研究。进行了形态测量以探究身体形态。首次对如此大量的标本分析了类蛭环节动物的消化系统和生殖系统。对佩氏棘蛭和利氏副棘蛭的观察揭示了所分析类群生殖系统的关键差异，主要涉及睾丸囊形状和卵巢囊长度的变化。消化系统分析结果表明，棘蛭目的吸血寄生虫可能也过着捕食性生活方式。所呈现的研究结果支持将棘蛭目分为棘蛭科和副棘蛭科的分类划分。还讨论了棘蛭目和蛭目之间的多个相似之处。
