The pressures responsible for the selection of "non-ectoparasitic" habitats in the Monogenea are discussed. It is suggested that certain monogeneans have become internal to reduce the pressures exerted by predators of ectoparasites rather than to avoid competition with other ectoparasites or to have access to better resources. The fact that these movements have concerned the Monopisthocotylea rather than the Polyopisthocotylea could be related to the different mode of invasion by oncomiracidia in these two groups. When Monogenea are internal in "non-fish" hosts, it is suggested that this has allowed them to survive the colonisation of terrestrial environments by vertebrates, a process of coevolution which was disturbed by lateral transfers.
本文讨论了在单殖吸虫中促使其选择“非体表寄生”栖息地的压力。研究表明，某些单殖吸虫进入宿主体内是为了减轻体表寄生虫捕食者施加的压力，而非为了避免与其他体表寄生虫竞争或获取更好的资源。这些迁移发生在单后盘目而非多后盘目，这一事实可能与这两类幼虫不同的侵入方式有关。当单殖吸虫寄生于“非鱼类”宿主的体内时，这可能使它们在脊椎动物对陆地环境的殖民过程中得以存活，这是一个因横向转移而受到干扰的协同进化过程。
