Facts

  • Adults of most species are of one sex throughout their lives (ref: Wiki)
  • The larvae of articulate species live only on yolk, and remain among the plankton for only a few days (ref: Wiki)

Discussion

  • Since larvae do not feed (see fact 2), no acceleration is assumed
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
