  • Produces a new house each 2 h (marine snow) (ref: Wiki)
  • dies at first spawning (ref: Wiki)


  • Reprod buffer builds up on trunk, so the basis growth with L^2, and contribution to total trunc length with N/L^2
  • Allocation to reproduction starts at birth, so E_Hp = E_Hb
  • Parameters tuned by hand
