Ocosia spinosa is also known as the spine, stone dog, stone fish. Ocosia spinosa, a tropical marine fish, is distributed in the western Pacific Ocean of Taiwan, with a depth of 288 meters. It is currently only found in Pingtung, which is located in southern Taiwan. The reason of its unique distribution is unknown.

Ocosia spinosa perches on the soft bottom of the edge of the continental shed and catches the small fish and crustacean by its camouflage ability and poisonous gland under the spine.

Morphological characteristics

The body of Ocosia spinosa is slightly longer 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 in the whole 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 Scorpeanidae.
