It is typically found in shallow waters, with a depth range extending to a few meters below the surface. This species is frequently observed in the intertidal zone, making it a common sight during low tides. The Aspasmogaster costata is a prevalent presence in the neritic zone, which encompasses the coastal waters extending from the shoreline to the edge of the continental shelf.
Taxonomy
