  • Ceratoglanis scleronema (Bleeker, 1862)

Distribution & Description

C. pachynemus originates from the Chao Phraya and Mekong River basins.[2] C. scleronemus occurs in the Pahang River basin of peninsular Malaysia, the Baram, Barito, Kapuas, and Rejang River basins of Borneo, Citarum River basin of Java, and the Batang Hari and Siak River basins of Sumatra.[2]

C. pachynemus grows to 28.0 centimetres (11.0 in) SL. It inhabits mainstream rivers. It is carnivorous, feeding on insects and benthic fauna.[3]

C. scleronemus grows to 44.0 cm (17.3 in) SL. In the Kapuas Lakes area in Kalimantan Barat, Indonesia, fishermen reported that this species inhabits rivers and major streams with moderate to fast current. It appears to be predatory in nature, feeding on aquatic invertebrates and fish.[4]

gollark: Applied Science was the second one in Spirit's list, no?
gollark: If it's just static content, I can add it to the endless list of random things on my website, but there would probably need to be a way to update it.
gollark: Time to save that on my notes thing somewhere and maybe pay attention to it eventually!
gollark: Is there a list of these "good" engineering YouTubers somewhere? I forgot the ones people were talking about earlier and I'm interested in new stuff to watch.
gollark: I totally would, assuming you count occasionally alt-tabbing to it sitting through it.
