This encompasses depths ranging from 0.0 to 40.0 meters, encompassing both shallow coastal waters and deeper portions of the continental shelf. The species is commonly found in neritic zones, characterized by their proximity to the shoreline and influenced by the continental shelf. These habitats often provide ample opportunities for the Abantennarius sanguineus to blend seamlessly with its surroundings and ambush unsuspecting prey.
