The National Center for Biotechnology Information does not indicate that any phylogenetic analysis has been published on Caballerorhynchus that would confirm its position as a unique order in the family Cavisomidae.

[1] It is distinguished from other genera of Cavisomidae through several morphological traits including the location of the testes (away from posterior extremity).

[7][8][9] The life cycle of an acanthocephalan consists of three stages beginning when an infective acanthor (development of an egg) is released from the intestines of the definitive host and then ingested by an arthropod, the intermediate host.

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

[16] There are no reported cases of C. lamothei infesting humans in the English language medical literature.
