Halocoryza is a of small, intertidal () restricted to tropical and subtropical coastal . The genus comprises four described distributed across shorelines of the Atlantic, Pacific, and Indian Oceans, including Caribbean islands and the Gulf of Mexico. All species are associated with sandy or coralline substrates near mangroves, coral reefs, or seaweed accumulations. The genus is characterized by reduced capability, slow running speed, and for burrowing in coastal sediments.
