Fun Facts
- The first dorsal spine of the scrawled filefish exhibits small notches along its length, resembling a file in appearance. This dorsal spine, then, contributes to the species common name.
- The primary dorsal spine can be made to stand erect. Such a posture is utilized by several members of the superfamily Balistoidea to lock themselves into a crevice or crack within a reef system – thus making predatory extraction difficult.
