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.
多骨頭蓋與前背的碟的多皺紋背面暴露出來;(不被皮膚蓋著) 在前背的 |碟上的在上枕骨冠與成對的銳利縱向的脊上的一個中央的銳利脊; 在頭側與身體有上的皮膚緊密地在一起 beadlike 或者相似大小的表面粗糙突起 (與壁虎皮膚的相似); 體高 7.9-9.3;(意謂 8.5) 在深色的條紋之間的身體側邊中途上的一個深色的斑點或斑塊伴隨著背鰭基底與脂肪的鰭了。 在髓棘上面的皮膚前面與後面的到脂鰭總是形成大的脊或者隆起 (七到九在脂鰭之前, 三到五個在後它), 多較突出而眾多的超過相當弱的隆起或者脊有時在 B. bagarius 中在髓棘之上形成而且很少地呈現甚至在 B. yarrelli 中的比較弱的發展. 在 B. suchus 中，脂鰭起源傾向位於甚至進一步在後部的超過在 B. bagarius( 因此更進一步的在後部地超過在 B. yarrelli) 中, 與距離分開背部與脂肪的鰭非常大在 B. suchus 超過在 B. bagarius 或 B. yarrelli.

Bayesian length-weight: a=0.00676 (0.00307 - 0.01489), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
