The ventral side, the edge of the second dorsal fin facing the body and the base of the pectoral fin are whitish. The tooth plates are two-tone and striped yellowish-gray. The spine in front of the first dorsal fin is just as long or slightly longer than the head. The elongated second dorsal fin is indented in the middle.
