Assuming that metagenesis is typical among the Semaeostomeae species (18 metagenetic life cycles over 20 descriptions of semaeostome species; Jarms, 2010; Morandini et al., 2013), this species is likely to have a metagenetic life cycle.
The maximum lifespan of echinoplutei remains an open question, as does, given the ability of these larvae to undergo cloning (Eaves and Palmer, 2003; Vaughn and Strathmann, 2008), the possibility that they afford echinoids the potential for metagenesis (Mortensen, 1921).
De esta forma aprovechando la metagenesis entre la microbiota y el organismo humano, el equipo de salud puede intervenir de manera favorable en la epigenesis del proceso salud-enfermedad-atencion.
