Every day during low tide, pairs of Great Blue Herons travel from a rookery at the head of Henderson Inlet to gather on the Nisqually Indian Tribe oyster farm. Whether the oysters are grown on the ground or suspended, the habitat they provide for smaller invertebrates draws forage fish who directly benefit from the abundant food source.

This is a photo showing the commensal relationship between sand dollars and geoduck. Geoduck survival is higher when sand dollars are present. It would appear they limit predation on the geoduck. It might be described as mutualism as it appears the sand dollars derive some benefit as well since they actively colonize geoduck beds.
