Species in the Salish Sea
Note: The list below is incomplete. You can assess the extent of its coverage by examining the references we used to assign species to this ecosystem. Note, however, that there are too many species of invertebrates for SeaLifeBase to provide you with complete species lists. You may be able to help us more on this list by sending us Internet sources or published references that we have not yet used for this ecosystem.
