Consequently, developmental constraints might have determined the development of the Osedax symbiosis in the somatic mesoderm.
In Osedax the trophosome--developed only in females (Rouse et al., 2004)--is formed by bacteriocytes and nonsymbiotic cells lying between the body wall muscle layer and a peritoneum in the ovisac and root region; thus it is derived from the somatic mesoderm (Katz et al., 2011).
