Evolution in the pentastomids

Abstract:
The Pentastomida, or tongue worms, form an aberrant group of annulated endoparasites little known to most parasitologists and veterinarians. Although there is no doubt of their affiliation to arthropods, textbooks often rank the Pentastomida as a separate phylum. Riley's many publications on the group have 'promoted it from the realm of the completely unknown to the semi-obscure', but still much research is needed on their basic biology, as little is known about their biochemistry, ecology or their evolutionary relationships. This review by Rolf Haugerud is intended to inspire curiosity about the Pentastomida by discussing their evolution in relation to their phylogeny, host relationships, geographic distribution, transmission and impact.
