  • Lives in symbiosis with sea urchin Meoma ventricosa (ref: BruyRiga2009)
  • Weight-length: family member Austinixa aidae of Carapace Width 1 cm has wet weight 0.2 g (ref: PierPezz2011)
  • Larval development consists of a prezoeal stage of 5 min, followed by three zoeal stages of 1, 2.1, and 2.7 days, respectively. The megalopa can be reached by day 6 (mean 6.8), the first crab instar by day 12 (mean 15.3). (ref: PohlTelf1983)


  • Males are assumed to differ from females by {p_Am} only
  • Egg production rate is unkown and guess is based on kap = 0.8
