Cystacanths of Acanthocephalus clavula Dujardin 1845 (Acanthocephala) were found in the hemocoels of naturally infected Echinogrammarus pungens M. Edwards 1840 (Amphipoda). Crustaceans were collected in Porto Frossone, an estuarine locality of the River Adige. Only 3 out of 562 E. pungens specimens were infected by A. clavula cystacanths; the larvae were enclosed in a thin acellular envelope. Infected amphipods were all females, and their total length was greater than that of uninfected females. Moreover, adult specimens of this acanthocephalan were found in the alimentary tract of Anguilla anguilla (L.) eels sampled in the crustacean collecting site. A description of cystacanths and their stages of development is reported here.
1845年杜雅尔丹发现的锁骨棘头虫（棘头虫纲）的囊尾蚴存在于1840年爱德华兹发现的自然感染的尖刺艾氏钩虾（端足目）的血腔内。甲壳类动物采自阿迪杰河河口地区的弗罗索尼港。562个尖刺艾氏钩虾标本中只有3个被锁骨棘头虫囊尾蚴感染；幼虫被包裹在一层薄的无细胞包膜中。受感染的端足目动物均为雌性，其总长度大于未受感染的雌性。此外，在甲壳类动物采集地采集的欧洲鳗鲡的消化道中发现了这种棘头虫的成虫标本。本文报道了囊尾蚴及其发育阶段的描述。
