Characteristics

''Pontinus'' scorpionfishes have very bony heads The head has 2 preorbital spines over the maxillary, 3-4 spines on the suborbital ridge although the first spine on the preorbital bone is frequently absent. There is a supplemental preopercular spine and the uppermost preopercular spine is the longest with the second preopercular spine being often absent, then the third and fourth are present but the 5th may be present or absent. They have both
