Etymology: Ceratoglanis: Greek, keras, -atos = horn + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Asia: Citarum drainage in Java, the Batang Hari and Siak drainages in Sumatra, the Pahang drainage in Peninsular Malaysia and the Baram, Barito, Kapuas, and Rejang drainages in Borneo. Reports of this species from the Chao Phraya drainage are misidentifications of Ceratoglanis pachynema.

Morphology | Morphometrics
soft rays: 98 - 108;
Vertebrae: 62 - 65. Snout with a steep ventral profile (ventral angle of snout 20°-26°), relatively more anal-fin rays (98-108), and smaller eyes (eye diameter 10.7% - 14.0% HL) that are set further apart (interorbital distance 35.4 - 40.9% HL). Mature males have membranous extensions on only the anterior edge of the maxillary barbel.
In Kapuas Lakes area in Kalimantan Barat, Indonesia, fishermen reported that this species inhabits rivers and major streams with moderate to fast current (Ref. 56749). Appears to be predatory in nature, feeding on aquatic invertebrates (Ref. 38651) and fish (Ref. 56749).
