Whereas the acceleration of cnidarian nematocysts is driven by high internal pressure, the dinoflagellates lack the necessary metabolic pathways. (sciencedaily.com)
Moreover, the presence of DMRT1 gene, also present in cnidarians, confirms «the great heterogeneity of sponges despite their simple morphology,» affirms the expert. (sciencedaily.com)
The comparative study is based on a comprehensive proteome analysis of isolated Cnidarian nematocysts by the Heidelberg researchers. (sciencedaily.com)
