  • Spawning over 4-6 months, several capsules per clutch, at least 2 clutches (ref: MaxwHanl2000)
  • typically lives for 1 yr, some reach 2 yr, and occasionally 3 yr (ref: Summ1971)
  • sex dimorphy, sex ratio 1:1; brood in july & nov (ref: Summ1971)
  • Programmed death, not by ageing (ref: Wiki)


  • Males are assumed to differ from females by {p_Am} and h_a only
