Description: The tidewater goby is a small grey-brown colored fish characterized by large pectoral fins and a ventral sucker-like disk formed by the complete fusion of the pelvic fins.

Diet: Tidewater gobies feed on small invertebrates, phytoplankton or zooplankton, depending on their size.

Habitat: The tidewater goby lives in coastal lagoons, estuaries, and marshes with relatively low salinities. Within GGNRA, they have been know to inhabit Rodeo Lagoon.
