简单描述
型态特徵 | 形态测量图
背的软条 (总数): 17-20; 臀鳍软条: 18 - 21; 脊椎骨: 52 - 54. Head relatively short, <39.5-0.025% SL. Snout short (22-28%HL); broadly triangular anteriorly when viewed from above. Orbit diameter about 1/5 to 1/4 HL, along the whole upper edge and on the separate elongate-shaped part of the lower-posterior part of the orbit are accumulation s of whitish connective tissue. Interorbital space very wide, ca. 17-30% HL, flat, narrows very slightly at the middle of the orbit. Upper jaw extends to below the center of the orbit. Branchiostegal rays 8-9. Transverse rows of scales above lateral line 60-65, 30-35 predorsal. Gill rakers' length less than gill lamellae length, and completely free at the base. Opercle has a projection at the lower anterior corner; subopercle has a wide posterior edge usually with no separate processes. Anus not shifted forward from the origin of the anal fin. Pyloric caeca 12-18 (Ref. 41471).
头部相当短的,<39.5-0.025% SL。 吻短 (22-28% HL); 宽广三角形前面地当从上方看了。 眼窝直径大约 1/5 对 1/4 HL, 沿着整个的上缘与在个别延长-形状部份上下面的-眼窝的较后面的部分是微白色连接着组织的积聚 s。 眼间隔非常宽的, 大约 17-30% HL, 平坦的, 狭窄的非常些微地在眼窝的中央。 上颌在眼窝的中心之下延伸到。 鳃条骨 8-9. 横跨的列鳞片在侧联机面 60-65,30-35 前背的。 鳃耙的长度少于鳃小片长度, 而且完全地在基底分离。 鳃盖的在下面的前面角落有一个突出; 子鳃盖有一个宽的后缘通常有没有个别的突起。 肛门不改变向前的从臀鳍起点。 幽门盲囊 12-18.(参考文献 41471)
