  • Total height is twice the style height (ref: Birk1974)
  • Planula does not feed anf settles quickly (ref: ADW)


  • Aging at individual level hardly occurs, since cell differentiation is reversible
  • A new bud is formed as soon as the earlier one steps off
  • Bud is treated similar to foetus
