  • polyps 2.3-24 mm high (including arms); 1-5 ephyrae per strobila; strobilation 24 d at 10 C; (ref: HolsSotj2007)
  • budding of scyphistomae is rare, especially at low temperatures (ref: HolsSotj2007)
  • Newly liberated ephyrae were able to catch and feed on living Artemia nauplii, and within a few days they could swim well in culture dishes (ref: HolsSotj2007)
  • It is a favourite food of the leatherback turtle (ref: Wiki)


  • Polyps are assumed to differ from medusae by {p_Am} and E_Hp only and by isomorphic growth
