Macracanthorhynchus
Macracanthorhynchus, also known as the giant thorny-headed worm of swine, is a member of the 
Oligacanthorhynchidae which contains many species. One species, "M. hirudinaceus", is a parasite which lives in the intestines of pigs and other suids, and very occasionally in humans or dogs. It causes enteritis, gastritis or peritonitis. Its life cycle includes beetles of the genus "Melolontha" as intermediate hosts. This species has many synonyms which include: "Echinorhynchus gigas" (Block, 1782), "Macracanthorhynchus gigas" (Block, 1782), "Echinorhynchus hirundinacea" (Palas, 1781), "Gigantorhynchus hirundinaceus" (Pallas, 1781), "Gigantorhynchus gigas" (Block, 1782), "Hormorhynchus gigas" (Block, 1782), "Taenia haeruca" (Pallas, 1776), and "Taenia hirundinaceus" (Pallas, 1781) The complete mitochondrial genome of "M. hirudinaceus" has been sequenced. The eggs have 4 membranes are 98 um long and have an elongation ratio of 1.85.

Another species, "M ingens", has eggs which have 3 membranes are 94 um long and have an elongation ratio of 1.66. It parasitizes the Raccoon ("Procyon lotor") in the United States.
