Discussion

  • Males are less bulky, hence they have a different shape coefficient, del_M, compared to females

Facts

  • Obligate parasite on large scyphomedusea, certainly in early stages (Ref: Ditt1987)
  • 2 generations per year: a rapidfly growing generation in summer, followed by a slower growing and overwintering generation (Ref: Ditt1988)
  • dry weight = 0.142 * wet weight (Ref: Ditt1991)
