Morphological characteristics

The body of Ocosia spinosa is long and laterally flat, and the front of the back is raised. The tear bone and the second eye have a spine; the front cap bone has four to five small spines. There are no scales on its body. The starting point of the dorsal fin extends to the top of the eye and the second spine is the longest and gradually becomes shorter. The body and fins are pink, and irregular spots with taupe are scattered on the head, body side and fins.

Some scholars incorporated this species into the former Tetrarogidae. But recent scholars have agreed to classify it as Scorpaenidae.
