The integument of the acanthocephalans Echinorhynchus gadi, Acanthocephalus lucii, Polymorphus minutus and Macracanthorhynchus hirudinaceus have been investigated by stereoscan and transmission electron microscopy. The absorptive surface is considerably increased by invaginations of the outer plasma membrane (pore canals and vesicles). The rate of this enlargement has been calculated using morphometric methods. The values range from 20 to 62. The values are compared to values obtained from other gutless parasitic helminths and from the free-living rotifers which are presumably to be regarded as closely related to the acanthocephalans.
利用立体扫描电子显微镜和透射电子显微镜对棘头虫类的多棘吻棘头虫、鲁氏棘头虫、微小多形棘头虫和蛭形巨吻棘头虫的体表进行了研究。外质膜的内陷（孔道和小泡）显著增加了吸收表面。已使用形态测量方法计算出这种增大的速率。其值范围为20至62。将这些值与从其他无肠寄生蠕虫以及与棘头虫类可能被认为密切相关的自由生活轮虫获得的值进行了比较。
