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..

Eastern Atlantic: common in coastal marine waters from Cap Blanc (Mauritania) to Gabon; occasionally enters estuaries and brackish waters (Ref. 57224). Reported from the middle Benue (Niger basin) in Nigeria (Ref. 3064, 57224). Reported as possibly as far south as Angola (Ref. 3876) but this is unconfirmed (Ref. 57224).

Descrição suscinta
Morfologia | Morfometria
Espinhos dorsais (total): 2; Raios dorsais (total): 7; Espinhos anais 0; Raios anais : 12 - 14. Diagnosis: body elongated and rounded; head broad and only slightly flattened above; snout rounded; mouth inferior; maxillary barbels reaching to pectoral fin bases, mandibular ones being shorter; osseous head shield fairly visible through the skin, coarsely rugose; occipital process rather narrow at base, tapering towards its distal end, with a median keel; predorsal plate short, very rugose and crescent-shaped; premaxillary teeth villiform, forming a plate slightly curved (Ref. 57224). Palatine teeth usually in a single pair of small rounded patches, widely separated, when present, by a space much greater than their diameter (Ref. 57224, 81640). Sometimes 1 or both patches absent; usually no, infrequently 1-2 tiny, gill-rakers on posterior face of 1st and 2nd branchial arch (Ref. 57224). Total number of anterior gill-rakers on first arch: 13-15 (Ref. 57224, 81640). 14-17 gill rakers on the outer side of the entire 2nd arch (Ref. 81640). Dorsal fin short with a long, osseous, more or less serrated spine preceded by a very short one; dorsal and pectoral fins with a strong serrated, erectile spine; adipose fin well developed; caudal fin forked, with long and pointed lobes (Ref. 57224).
Coloration: olive-brown above, silvered on sides, belly white (Ref. 57224).
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.
