These scales, particularly those on its head, contribute to its name “Largescaled Spiny Flathead”. Its coloration varies, often blending with the surrounding environment, making it difficult to spot amidst the seafloor.
Habitat and Occurrence
Onigocia spinosa is found in a variety of marine zones, inhabiting depths ranging from 8.0 to 250.0 meters. This wide depth range allows this species to thrive in various ecosystems, from the shallower continental shelves to the deeper oceanic waters. The Midget Flathead, Largescaled Spiny Flathead, Spiny Flathead is a common inhabitant of the benthic zone, the seabed environment. It prefers to live on sandy or muddy bottoms, often hiding amongst rocks and coral reefs, camouflaged by its coloration.
