First insight into metal binding proteins from the de novo transcriptome of acanthocephalan parasite Dentitruncus truttae [PDF]
Scientific ReportsAcanthocephala are parasites increasingly used as bioindicators of environmental quality due to their ability to effectively accumulate metals. However, the mechanisms of metal homeostasis in them remain unclear as there has been only one genomic study ...

SEM study of hooks in the Acanthocephala with emphasis on structural-functional relationships
Zoodiversity, 2022 The retractable proboscis of acanthocephalans is equipped with hooks for attachment to the intestine of the definitive host. Throughout their evolutionary history, acanthocephalans have developed a variety of ways to maximize their anchoring to host gut ...
