  • Common ctenophore in the West Coast of united states (ref: Wiki)
  • Hermaphrodites and breeding can occur at all sizes (ref: jellieszone)
  • Nice video of feeding (ref: youtube)


  • Chemical pars are assumped to relate to ash-free dry mass; MaleFaga1993 report ash free dry mass over dry mass ratio of 0.263 - 0.297 with mean 0.279, which makes del_W = 3.5842
  • Length measurements from Hiro1972 are equatorial length but more recent studies use polar length
  • growth and reprod expectations of indivduals A,B,C use measured ingestion as forcing functions
