[1] The National Center for Biotechnology Information does not indicate that any phylogenetic analysis has been published on any Euzetacanthus species that would confirm its position as a unique order in the family Arhythmacanthidae.

Exceptions to this taxonomy include: E. simplex where the lemnisci are slightly larger than the proboscis receptacle, in E. chorinemusi and E. golvani only the anterior body end is dilated.

[3] Euzetacanthus species consist of a cylindrical proboscis covered in hooks and a spineless trunk.

This stage involves penetrating the wall of the mesenteron or the intestine of the intermediate host and growing.

[3] There are no reported cases of Euzetacanthus infesting humans in the English language medical literature.
