Summary:
A creamy-tan stargazer with two prominent broad dark brown bands across the back, one above pectoral fins and the another below the rear of the dorsal fin, brown lines radiating from the eyes, pale cheeks, a dark brown band on the upper part of the gill cover, a large dark brown spot on top of head, and brownish caudal and pelvic fins with white margins.
Although easily recognised by the distinctive spot on the head and prominent rear outline to the bony covering of the head, this species is rarely seen by anglers due to its deepwater habitat.
