Actinopterygii (ray-finned fishes) > Siluriformes
(Catfish) > Ariidae
(Sea catfishes) > Ariinae
Etymology: Carlarius: First part of the generic name honors Dr. Carl Ferraris, Research Associate at the California Academy of Sciences for his contribution to the knowledge of Siluriformes fishes and continuous support and encouragement throughout the development of this work; the second part is from the frequently used generic name Arius..

Max length : 83.0 cm TL male/unsexed; (Ref. 40637); common length : 35.0 cm TL male/unsexed; (Ref. 2683); max. published weight: 8.5 kg (Ref. 40637)
Eastern Atlantic: Cape Blanc, Mauritania to Gabon and possibly Angola along the shallow continental shelf. Reported from the lower Niger basin, the Benoué River (Ref. 13331), and the Gambia (Ref. 28587).
Enters brackish waters; found along the shallow continental shelf (Ref. 3876). Feeds on benthic invertebrates buried in the mud but it can sometimes leave the bottom to capture prey in open water. The females bear large eggs which are incubated and develop in the buccal cavity of the males. The rays of the fins are venomous and the wound inflicted is extremely painful (Ref. 5377). Minimum depth from Ref. 58018.
