The armored catfish (Cranoglanididae) are a fish family with only one genus ( Cranoglanis ) from the order of the catfish-like (Siluriformes). They are mainly found in large rivers in southern China and Vietnam .

features

Armored catfish are medium-sized catfish with a laterally flattened, scaleless body. It is named after a rough bone plate on the top of the head. They have large eyes and four pairs of barbels . The dorsal fin is short and has one hard and six, less often five, branched soft rays. The caudal fin is deeply forked. The anal fin is elongated and has 35 to 41 soft rays, the pelvic fins have 12 to 14 soft rays. The pectoral fins have a strong hard ray. The teeth are small and absent on the palatine bone and ploughshare .

Systematics

In the classical system, the armored catfish are the only family of the superfamily Cranoglanididea. Molecular biological investigations, however, indicate a position together with the catfish (Ictaluroidae) in the superfamily Ictaluroidea.

The family includes only one genus with five species :

• Cranoglanis Peters , 1881
  • Cranoglanis bouderius ( Richardson , 1846)
  • Cranoglanis caolangensis Nguyen , 2005
  • Cranoglanis henrici ( Vaillant , 1893)
  • Cranoglanis multiradiatus ( Koller , 1926)
  • Cranoglanis songhongensis Nguyen , 2005
