| Data | Generalised animal | Luidia sarsii | Unit | Description |
|---|---|---|---|---|
| v | 0.02 | 0.02061 | cm/d | energy conductance |

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)
