脊椎骨: 40 - 42. Rugose dorsal surface of bony cranium and predorsal plate exposed (not covered by skin); a median sharp ridge on supraoccipital crest and paired sharp longitudinal ridges on predorsal |plate; skin on sides of head and on body with closely set beadlike or granular protuberances (resembling those of gecko skin) of similar size; body depth 7.9-9.3 (mean 8.5); a darkly pigmented spot or blotch on side of body midway between darkly pigmented bands associated with bases of dorsal and adipose fins. The skin above the neural spines anterior and posterior to the adipose fin always forms large ridges or humps (seven to nine in front of the adipose fin, three to five behind it), much more prominent and more numerous than the relatively weak humps or ridges sometimes formed over the neural spines in B. bagarius and rarely present and even more weakly developed in B. yarrelli. In B. suchus the adipose fin origin tends to lie even further posterior than in B. bagarius (and therefore much further posteriorly than in B. yarrelli), and the distance separating the dorsal and adipose fins is much greater in B. suchus than in B. bagarius or B. yarrelli.
多骨头盖与前背的碟的多皱纹背面暴露出来;(不被皮肤盖着) 在前背的 |碟上的在上枕骨冠与成对的锐利纵向的脊上的一个中央的锐利脊; 在头侧与身体有上的皮肤紧密地在一起 beadlike 或者相似大小的表面粗糙突起 (与壁虎皮肤的相似); 体高 7.9-9.3;(意谓 8.5) 在深色的条纹之间的身体侧边中途上的一个深色的斑点或斑块伴随着背鳍基底与脂肪的鳍了。 在髓棘上面的皮肤前面与后面的到脂鳍总是形成大的脊或者隆起 (七到九在脂鳍之前, 三到五个在后它), 多较突出而众多的超过相当弱的隆起或者脊有时在 B. bagarius 中在髓棘之上形成而且很少地呈现甚至在 B. yarrelli 中的比较弱的发展. 在 B. suchus 中，脂鳍起源倾向位于甚至进一步在后部的超过在 B. bagarius( 因此更进一步的在后部地超过在 B. yarrelli) 中, 与距离分开背部与脂肪的鳍非常大在 B. suchus 超过在 B. bagarius 或 B. yarrelli.
Inhabit large rivers (Ref. 12693). Usually associated with rapids (Ref. 43281). Feed on fishes. Sold fresh, although the value of its meat is limited because it spoils rapidly and can cause illness (Ref. 12693).
