簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 87; 臀鰭軟條: 73; 脊椎骨: 48. This species is distinguished from all congeners by the combination of: ID pattern1-2-2-2-2; caudal-fin rays 12; vertebrae; 9 (3 + 6) abdominal, 48 total; hypurals 4; D 87, A 73; longitudinal scale rows 64; transverse scale rows 25; scale rows on the head posterior to the lower orbit 15; body elongate (BD = 24.9% of SL); preanal length long (PAL = 28.1% of SL); upper head lobe much smaller than lower lobe; head long (HL = 24.2% of SL), longer than head width (HW/HL = 0.97); postorbital length long (POL = 76.5% of HL); snout short (SNL = 10.4% of HL, SNL/ED = 1.25), slightly rounded anteriorly; dorsal-fin origin located at the vertical posterior to upper eye; predorsal length short (PDL = 18.1% of HL); eye is relatively small (ED = 8.4% of HL); eyes are unequal in position with anterior margin of upper eye greatly in advance of anterior margin of lower eye; fleshy ridge well developed on posterior part of ocular-side lower jaw; membrane covering upper and lower eyes; with continuous, fleshy membrane connecting anterior nostril with lower part of eye. Colouration: ocular-side pigmentation uniformly yellowish-brown; blind-side pigmentation uniformly yellow; both sides with obvious dermal spots on bases of anteriormost dorsal and anal fins (Ref. 126065).
Presumably frequents coastal lagoons with sandy bottom. More studies are needed concerning the ecology of this species.
推測為常常聚集於岸邊潟湖且底部為沙地的地方。 更多的研究被需要關於這種的生態學。
