Resumen:

Acanthocephalans are an enigmatic group of endoparasites with complex life-cycles that involve vertebrates as final definitive hosts and invertebrates as intermediate hosts. The name of the phylum refers to the attachment organ commonly known as a proboscis. The proboscis is variable in shape and is covered by a tegument within which are embedded the roots of recurved, sclerotized hooks. Hooks are the structures that allow these parasites to attach to the intestinal wall, causing on some occasions severe damage to their definitive hosts. The proboscis shape, and the number, size and arrangement of hooks, are taxonomic traits that have been traditionally used to classify approximately 1300 described species distributed worldwide (Amin, 1987; Poulin & Morand, 2004; Kennedy, 2006; Amin, 2013; Figure 9.1). © Cambridge University Press 2015.
