Myxozoans are highly derived cnidarians that have undergone dramatic evolution from a free swimming, self-sufficient jellyfish -like creature into their current form of obligate parasites composed of very few cells.

Myxozoans are highly diverse and globally distributed cnidarian endoparasites in freshwater and marine habitats. They have adopted a heteroxenous life cycle, including invertebrate and fish hosts, and have been associated with diseases in aquaculture and wild fish stocks.

Members of the Myxozoa are microscopic metazoan parasites with an extremely reduced body. The dimensions of the myxospore, the typical myxozoan stage in fish hosts, range usually between one hundredth and two hundredth of a millimetre.

Myxozoans are metazoan (multi-celled) parasites of invertebrates and fishes in both marine and freshwater environments. Though less common, some myxozoans infect amphibians, reptiles, birds, and mammals.

Myxozoa are endoparasitic animals exhibiting complex life cycles that in most known cases involve two hosts: a vertebrate (usually fish, but also rarely amphibian, avian, or mammalian) intermediate host and an invertebrate, mostly annelid or …

2015年1月1日 · Can we discern any evolutionary trends within the Myxozoa and how can we practically recognise species given the extreme morphological simplification that characterises the group? Our first six contributed chapters focus on these and other issues.

This book provides an up-to-date review of the biology of myxozoans, which represent a divergent clade of endoparasitic cnidarians. Myxozoans are of fundamental interest in understanding how early diverging metazoans have adopted parasitic lifestyles, and are also of considerable economic and ecological concern as endoparasites of fish.

Myxozoa is a speciose group of endoparasitic cnidarians that can cause severe ecological and economic effects. Their cnidarian affinity is affirmed by genetic relatedness and the presence of nematocysts, historically called “polar capsules”.

2015年4月1日 · Myxozoans evolved as an endoparasitic radiation of cnidarians exploiting invertebrate and vertebrate (primarily fish) hosts in freshwater and marine environments. Currently, there are some 2,200...

Myxozoans are a diverse group of microscopic parasites that infect invertebrate and vertebrate hosts. The assertion that myxozoans are highly reduced cnidarians is supported by the presence of polar capsules, which resemble cnidarian stinging structures called “nematocysts.”
