Echiura - Devolopment of the nervous system and phylogenetic implications
Immunohistochemical analysis (cLSM) of the development and organization of the nervous system in Echiura and the phylogenetic implications of these results. The work of Rene Hessling shows volume rendered three-dimensional reconstructions of the central nervous system of Bonellia viridis. The results suggest that the Echiura do not form a distinct phylum but should be consided as a subtaxon of Annelida.
