Rhepoxynius abronius (Amphipoda; Phoxocephalidae) is a predominantly subtidal species of the North American Pacific coast. It is also found sub- and intertidally within the polyhaline region of estuaries of Oregon and Washington. Within the Yaquina Bay estuary, Oregon, R. Abronius is an annual species producing one or two broods per year. Recruitment occurs over an extended period from mid to late winter through summer. Mortality was 20-25 percent per month. The annual range in biomass was 40-180 mg ash-free dry weight (AFDW)/0.5 sq. m.
