  • At metamorphosis, juvenile C. fleckeri medusae are approximately 1.2 to 1.4 mm in size (ref: GordSeym2012)
  • Age determination: daily growth rings in s tatoliths in statocysts of cubomedusae rhopalia (eye bearing sensory structures) C. fleckeri medusae undergo an ontogenetic shift in their cnidome (and diet) that potentially explains the lethality of larger medusae to humans at 60--100 mm IPD [52], a size they would reach after ,50--65 d (ref: GordSeym2012)
  • At metamorphosis, juvenile C. fleckeri medusae are approximately 1.2 to 1.4 mm in size (ref: CarrAlde2002)
  • nematocyst ratio changed with increasing size, with mastigophores (nematocysts believed to hold the lethal venom component for prey) increasing in proportion. The change in cnidome ratio is correlated with a change in the prey of C. fleckeri with increased size. Small C. fleckeri appeared to feed exclusively on prawns, medium sized animals fed on fish and prawns and large animals fed predominantly on fish. (ref: GordSeym2012)
  • When the polyp has reached its maximum size and receives certain environmental stimuli, it begins to metamorphose into a medusae (ref: jcu)
