Snails serve as intermediate hosts supporting the larval development of almost every one of the 10,000 described species of digenetic trematodes. The majority of these infections result in diseases of humans or animals that cause profound medical and agriculture burdens. Snails place significant selective pressure on tremaotdes, acting as a filter for those that they encounter. In many cases, only a single species of snail is suitable as a host for a trematode species. A result of this specificity is that the geographic distribution of the human and animal diseases caused by adult trematodes is defined by the presence of susceptible snail hosts.

蜗牛作为中间宿主，支持着所描述的 10,000 种双遗传吸虫中几乎每一种的幼虫发育。这些感染大多数会导致人类或动物疾病，造成严重的医疗和农业负担。蜗牛对吸虫施加了巨大的选择压力，充当它们遇到的吸虫的过滤器。在许多情况下，只有单一种类的蜗牛适合作为吸虫物种的宿主。这种特异性的结果是，由成年吸虫引起的人类和动物疾病的地理分布是由易感蜗牛宿主的存在决定的。
