|Scientific Name||Clarias pachynema Boulenger, 1903|
|Type Locality||Ja R., s. Cameroon.|
|Synonym(s)||Clarias esamesae, Clarias oxycephalus|
|Pronunciation||klar ee ass|
|Etymology||Clarias: From the Greek chlaros, meaning lively; in reference to the ability of the fish to live for long periods out of water.|
|Size||320mm or 12.6" SL. Find near, nearer or same sized spp.|
|Identification||Clarias species are characterized by having an elongated body; a soft rayed dorsal fin extending to, or nearly to, the caudal fin base; a soft rayed anal fin extending from just behind the anus to the caudal fin base; pectoral fins each with a serrated anterior bony spine; head depressed, covered largely by firmly sutured, surface sculptured bony plates forming a protective helmet; four pairs of flagellate barbels (nasals, maxillaries, inner and outer mandibulars); air breathing organs derived from the 2nd and 4th epibranchials within a superbranchial chamber.
Head pointed in dorsal outline; snout short; eyes dorsally located. Frontal fontanelle long and narrow (`knife-shaped'); occipital process long and oval-shaped. The `dermosphenotic' and supraorbital bones joined in specimens over 80 mm SL. Tooth plates small. gill rakers long, slender and distantly set. Suprabranchial organ well developed. Openings of the secondary sensory canals regularly arranged on flanks.
|Sexing||The genital papilla, which is to the right of the anus as you look at the fish with its head to the left, is elongated and pointed in males while it is round and relatively larger (and larger than the anus) in females. In ventral view especially, females are much broader in the body than males of equal age and rearing practices.|
