水蛭属于Ozobranchus属，寄生在海龟和淡水海龟身上。淡水物种O.生活在日本的日本细胸鳃金龟（Ozobranchus jantseanus）被认为是一个非本土物种，因为它们的主要宿主是近几个世纪从邻近的亚洲国家引进的瑞氏水龟（Mauremys reevesii）。为了评估日本人口是否ofO。jantseanus可能已被引入，其遗传多样性进行了研究，使用线粒体细胞色素氧化酶亚基I序列。该物种的序列多样性很低，并且在日本的历史记录表明，日本的OofO。jantseanus可能是与它们的宿主海龟一起沿着人工引入的。COI的分子遗传学分析表明，两种海水Ozobranchus与淡水O. jantseanus。
Leeches belonging to the genusOzobranchusare ectoparasitic on sea and freshwater turtles. The freshwater speciesO. jantseanushas been recorded from China and Japan.Ozobranchus jantseanusinhabiting Japan is considered to be a non-indigenous species, because their primary host, the Reeves' pond turtle,Mauremys reevesii, is thought to have been introduced in the last few centuries from adjacent Asian countries. To assess whether the Japanese populations ofO. jantseanuswere likely to have been introduced, their genetic diversity was investigated using mitochondrial cytochromecoxidase subunit I sequences. The very low sequence diversity as well as the historical record of this species from Japan suggest that Japanese populations ofO. jantseanusmay have been artificially introduced along with their host turtles. Molecular phylogenies of COI showed that two marineOzobranchusspecies formed a clade together with the freshwaterO. jantseanus.
