Abstract The nervous system of the 1150 species-containing Acanthocephala is strongly influenced by their parasitic lifestyle. Also known as ‘thorny-headed worms’, these few-centimetre-long animals are endoparasites, having insects or crustaceans as intermediate hosts and vertebrates as final hosts.

Copulation of Acanthocephalus anguillae (Acanthocephala)
Parasitology Research, 2000A total of 114 specimens of brown trout, Salmo trutta Linnaeus, 1758, was sampled by electrofishing between October 1998 and July 1999 from the Ceresone stream (North of Padua, Italy). Over 63% of fish were infected with three species of helminth: a tapeworm, Cyathocephalus truncatus (Pallas, 1781), and two acanthocephalan species, Echinorhynchus ...

Morphogenesis of the Acanthocephala
International Journal for Parasitology, 1987Abstract Postzygotic development of acanthocephalans is described. The major conclusion that can be drawn is that there has been a great deal of speculation, and that there are still many questions left unanswered. For example, exactly when does the acanthor become a complete syncytium? Is the formulation of the central nuclear mass really homologous

Los acantocéfalos constituyen un grupo monofilético de helmintos exclusivamente parásitos. Presentan una probóscide espinosa en el extremo anterior a la que le deben su nombre (del griego acantha: espina y kephale: cabeza) y mediante la cual se fijan a los tejidos de su hospedador. Son endoparásitos obligados del intestino de vertebrados y presentan un
