Excerpt from The Genus Gyrocotyle, and Its Significance for Problems of Cestode Structure and Phylogeny
Monticelli discusses the question whether Mactra edulis is to be regarded as the true intermediate host of G. Rugosa, and con cludes that, since the example found in the mollusk contained hooked embryos, a third host must be found to convey G. Rugosa to Mactra. He suggests that possibly some of the mollusks on which Chimaera monstrosa feeds (probably some member of the Cyprinidae), may be the intermediate hosts of G. Urna.

Paperback. Condition: New. Print on Demand. This book examines the genus Gyrocotyle, a parasitic flatworm that inhabits the spiral valve of the Chimaera, a fish from the Chimaeridae family. This group of fish is primitive and has existed for millions of years, possibly evolving alongside the parasitic Gyrocotyle. The first recorded parasite was found in 1842 and since then, there have been four species identified: G. rugosa, G. urna, G. nigrosetosa, and G. mbriata (identified by the author). The text reviews the history of the study of Gyrocotyle, including the debate regarding its classification, habitat, and orientation. The author delves into its morphology and its place within the Cestodaria order, describing the digestive and reproductive systems. Further, the book details the complex behavior of the parasite, including its life cycle, locomotive capabilities, and responses to stimuli. This book's detailed analysis of Gyrocotyle's structure and behavior provides important insights into the evolution and biology of this ancient parasite. Understanding the Gyrocotyle contributes to a greater understanding of the evolution of cestodes, the most juvenile of the Platyhelminthes, which have themselves been evolving alongside vertebrates for millions of years.
