Hungry starfish which had not fed for two months, worked their way across the current until their olfactory tube feet, located near the tips of their arms, smelt an edible prey item after which they begin to travel up-current towards the source of the odour. Moving upstream in this way had the advantage that the prey was less likely to detect the approach of the starfish. Well fed starfish wandered in a more random fashion.

a layer on the seabed and the females later release their eggs on top. The females brood the developing eggs for four months but that is probably more to keep them clean and healthy and prevent predation than to speed their development as unbrooded eggs were found in the laboratory to develop at the same rate as brooded ones.

Breeding takes place when the water temperature falls to about 2 °C (36 °F) and the day length is at its minimum. Over a period of seven to eight weeks the normally solitary starfish begin to aggregate, eventually some climbing on top of others. The males release sperm which accumulates in
