Eastern Pacific: Palos Verdes in southern California, USA to Peru.
Inhabit estuaries, stagnant ditches or creeks of low current velocity between the sea and an elevation of 30 m. Benthic and most abundant on sandy and muddy bottoms. Ingests much mud and detritus, although also filter plankton (Ref. 36880). Found in shallow inshore areas; typically in freshwater but moves freely into the sea.
