簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 2; 背的軟條 (總數): 6; 臀鰭軟條: 19 - 22. Distinguished from S. elongatus by having modally 9 pectoral rays; 21 anal-fin rays; 16 gill rakers; large vomerine tooth patches, almost always fused; a more robust, deeper head and body; body somewhat compressed laterally; mental barbels equal or anterior to gular apex. Differs from S. cuspicaudus in having rounded caudal fin lobes and more robust body; from S. trigonocephalus by premaxillary tooth patch length being 1.5 to 2.5 times its width; trenchantly differs from S. maniradii in having only 13-18 gill rakers. Additionally, other distinguishing characters include, pelvic fins that contact or nearly reach anal fin origin when depressed and presence of thin plates or ossicles (highly variable in shape) extending vertically on anterior lateral line in most large adults (Ref. 57983).
與 S. elongatus 典型地藉著具有 9個胸鰭鰭條區分了; 21個臀鰭棘條; 16個鰓耙; 大的犛骨牙齒區塊,幾乎總是融合了; 一個更結實又比較深的頭部與身體; 身體略微扁長形的側面地; 神經觸鬚等於或者位於前喉部的尖頂。 有別於 S. cuspicaudus 有圓形的尾鰭葉與比較結實的身體; 從在 1.5 到 2.5 的上頜骨前齒列長度的 S. trigonocephalus 倍於它的寬度; 在只有 13-18個鰓耙方面銳利地有別於 S. maniradii 。 附加地，其他的有區別的特徵包括, 連絡的腹鰭或者幾乎達成臀鰭起源當扁平的而且有薄盤或者垂直地延伸的小骨 (高變異的在外形上) 在大多數的大成魚中在前面側線.(參考文獻 57983)
