背棘 (总数) : 1. The head is rounded and flattened on the upper part. The mouth is slightly inferior. It has 3 pairs of barbels (1 pair of maxillary barbels and 2 pairs of mandibular barbels. The cephalic surface is very rough (Ref. 35381).
头部是圆形的而且在上半部上平的。 嘴巴些微下方。 它有三对触须 (1对上颌骨触须与 2 对颚的触须。 头部的表面非常粗糙。 (参考文献 35381)
Confined chiefly to turbid waters in estuaries and the lower parts of rivers. Its delicate flesh is highly valued (Ref. 27188). Two annual cycles of slower growth are know during the two dry seasons (March and August to November). Probably has a short life span. In the beginning of reproduction, the male's mouth changes to function as a egg repository (buccal incubation). The female lays down her eggs in a sandy depression, then after fertilization, the male puts the eggs into its mouth which is provided with ventilation until hatching. Eggs diameter is about 2 mm and its number varies from 100 to 165 per female. Feeds mainly on crustaceans (Ref. 35381). Marketed fresh and salted.
主要地对在河的河口与下面部份中的浑浊水域限制了。 它的鲜美的肉高度地被评价。 (参考文献 27188) 缓慢生长的一年两次的周期在两者乾季 (三月与八月到十一月) 的时候已知是。 可能有一个短的寿命。 在繁殖的起点中，雄鱼的嘴变成功能作为一个卵容器 (口的孵育). 母鱼在一个沙地凹洼中产下她的卵, 然后在受精之后, 雄鱼把卵放入它的嘴是以通风提供直到孵化。 卵径是大约 2 mm ，而且它的数字每母鱼从 100 改变到 165 。 主要吃甲壳动物。 (参考文献 35381) 在市场上销售生鲜地了与盐腌的。
