Discussion

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

Facts

  • 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)
