Size 700mm or 27.6" SL. Find near, nearer or same sized spp.
Identification 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 i n 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.
Sexing Unknown.
