Three zonal scale rows on body; a scale row of small ctenoid scales under the ventral scale row (Ref. 559). Four preopercular spines, the 2nd longest and simple, the 4th flattened; the first dorsal spine longer than the 2nd (Ref. 559).
Body shape (shape guide): elongated.
Oviparous. Non-copulatory. However according to one study, presence of fertilized eggs in the ovary may have resulted from spermatozoa entering the ovary through the ovarian fluid during spawning, and consequently fertilizing unspawned eggs in the ovaries (Ref. 47168). Fertilized eggs in the ovary develop abnormally however, due to the unavailability of needed elements such as oxygen in the ovary (Ref. 47168).
