Genome sequencing confirms that myxozoans, a diverse group of microscopic parasites that infect invertebrate and vertebrate
hosts, are actually are «highly reduced»
cnidarians — the phylum that includes jellyfish, corals and sea anemones.
The apparent link between environmental stress and degraded coral health, and the recent information demonstrating the complexity of the
cnidarians, highlights the need to now understand the biology of the coral
host and
host responses in these patterns of change.
