简单描述 型态特徵 | 形态测量图

背棘 (总数): 2; 背的软条 (总数): 7-8; 臀棘 3-4; 臀鳍软条: 6 - 8. Diagnosis: head width usually less than 2/3 of standard length (Ref. 57126). Snout long and pointed, generally greater than half the head length in adults (Ref. 28714), length more than 0.9 times the head width in adults (less in juveniles) (Ref. 57126). Hind margin of adipose fin rounded; premaxillary dentition forming (in adults) two close-set oval plates (Ref. 57126). Maxillary barbel often blackish and only rarely reaching to anterior margin of opercula (Ref. 57126), usually not reaching beyond eye and much shorter than outer mandibular barbel (Ref. 28714, 81642). 8-12 (usually 10 or 11) gill rakers on lower limb of first gill arch; palatine membrane with multiple invaginations, 1-4 of them forming longer lobes; dorsal margin of cleithral process ending in a point (visible only in adults)(Ref. 57126).
头部大的很重地具有建造身体.(参考文献 4967) 有大理石花纹,否则有斑点的灰色,具有一些排列成列的黑色斑点。

生物学特性     字汇 (例如 epibenthic)

Inhabits lakes and large rivers (Ref. 4967). Has never been observed in large quantities in forested areas (Ref. 57126). Occurs in shallow water with muddy bottom. Bottom feeder, omnivore, feeds on plankton, seeds, detritus (Ref. 13868), mollusks (Ref. 13868, 28714), mud, debris (Ref. 28714), insect larvae (Ref. 6868, 28714), worms and small Crustacea (Ref. 6868). Oviparous (Ref. 205). Nested eggs are guarded by the male parent (Ref. 47642). Furthermore, the male plays host to eggs and young of Dinotopterus cunningtoni which takes advantage of the already prepared nest and feed on the host brood (Ref. 49546). An example of interspecific brood care.

栖息于湖与大河。 (参考文献 4967) 出现于浅水区底部为泥质的地方。 杂食动物, 吃浮游生物,软件动物,种子与碎屑。 (参考文献 13868) 卵生的.(参考文献 205) 被筑巢的卵被由雄鱼父母保卫。 (参考文献 47642) 此外,雄鱼担任的寄主卵与利用已经准备的巢的 脂鳍胡鲶〔Dinotopterus cunningtoni〕 的幼鱼并且吃寄主窝.(参考文献 49546) 一个种间窝照料的例子。
