  • One of the distinct individuals forming a colonial animal such as a bryozoan or hydrozoan.
  • Neuronal GSX expression, as reported from several hydrozoan and anthozoan species, is clearly more significant. PLoS ONE Alerts: New Articles
  • Hydra magnipapillata full genome and have not been identified until now in other hydrozoan or scyphozoan species, being only known from the anthozoan PLoS ONE Alerts: New Articles
