  • At metamorphosis, the sea star steps off its larva, which continues life for several more months. The star absobs all larval tissue in other Luidia species (ref: Wiki)
  • Feeds exclusively on Ophiura albida, Amphiura filiformis and Echinocardium cordatum (ref: Fenc1965)


  • growth dWw is used to estimate feeding level f_dW, to obtain digestion efficiency kap_X from J_X
