Facts

  • Sexes separated (ref: Wiki)
  • Trochophora short living in mothers burrow; eggs in a jelly, which serves as food (ref: FarkBerg1979)
  • Spawning early Oct; predation on tails reduce weight (ref: BeukVlas1979)

Discussion

  • exclude low tW values for old individuals; probably tail-eating
  • tW data composed from 2 figs on "small" and "big" worms, assuming that the "big" worms are second-years worms and that shrinking relates to predation of tails
