They are typically found in the intertidal zone, where they are exposed to the air during low tide. The Engina zonalis is a common species in the Indo-Pacific region, ranging from the Red Sea and the eastern coast of Africa to the Pacific Ocean, including Australia and New Zealand. They are found in a variety of marine zones, including the neritic zone, which extends from the shoreline to the edge of the continental shelf, and the oceanic zone, which encompasses the vast open ocean.
