🐟 Physical Description

Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 11 - 13; Anal spines: 3; Anal soft rays: 10 - 12; Vertebrae: 34. Diagnosis: The oblique mouth, a prognathic lower jaw, a small knob at the synthesis of the dentaries, the absence of distinct bars or stripes, the closely-spaced teeth, and lack of beak-like premaxillaries place this species in Diplotaxodon . Diplotaxodon dentatus has a smaller body depth, 26.4-28.4% of standard length, than D. altus (35.1-37.8%), D. greenwoodi (34.2-36.5%), D. macrops (33.9-37.6%), D. apogon (32.4-37.3%), D. aeneus (34.3-37.1%) and D. ecclesi (35.5%); there are more gill rakers on the first ceratobranchial in D. dentatus than in D. longimaxilla, 23-27 vs. 16-21; it has fewer teeth in the outer row of the left lower jaw, 17-25, that are exposed when the mouth is closed and more widely spaced than those of D. limnothrissa, 36-46, which are close together and embedded; it has a shorter snout length, 26.6-29.2% of head length, than D. argenteus, 31.7-34.2%, a longer post-orbital head length, 39.0-41.7% of head length vs. 37.7-38.8%, a narrower cheek depth, 10.6-15.2% of head length vs. 15.3-17.0%, generally more gill-rakers on the first ceratobranchial, 23-27 vs. 20-23, and a greater distance between the anterior origin of the dorsal fin to the posterior insertion of the anal fin, 50.3-53.1% of standard length vs. 49.6-51.2% .
