Introduced organisms have become the dominant invertebrate species in San Francisco Bay marshes and associated mudflats. This chapter focuses on epifaunal (surface-dwelling) and benthic infaunal (underground) invertebrates. Case studies drawn from a few well-studied organisms describe their history of introduction and ecological impacts. Topics include major pathways of introduction, general patterns, ecosystem engineers, competition and predation, and interactions among invaders. Some introduced invertebrates have had negative ecological impacts while others' impacts may be neutral or may benefit other species.

Keywords: salt marsh; mudflat; invertebrates; estuarine; epifauna; infauna; impacts; ecosystem engineers; competition
