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.
More on author: Günther.
Taxonomic Remarks
A. latiscutatus has been considered as a junior synonym of A. gambensis (Bowdich, 1825) (e.g. Ref. 89460). According to Ref. 6541, the latter is evidently a species of Arius, but the description is inadequate to confirm its identity.

marino; salobre demersal; rango de profundidad ? - 70 m (Ref. 6541), usually ? - 30 m (Ref. 6541). Tropical; 21°N - 17°S, 26°W - 11°E
Eastern Atlantic: coastal waters from Senegal to Angola (Ref. 3546, 3876, 7367, 57224). One record from Fernando Poo (Ref. 6541, 89460). Also reported from various river estuaries.
Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 27.5, range 27 - 28 cm
Max length : 85.0 cm TL macho / no sexado; (Ref. 33115); common length : 40.0 cm TL macho / no sexado; (Ref. 2683)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 7; Espinas anales: 0; Radios blandos anales: 13 - 14. Diagnosis: body elongated and rounded, head broad and only slightly flattened above, snout rounded, mouth inferior; osseous head shield coarsely rugose, fairly visible through the skin; occipital process prominently broad at base, tapering posteriorly, with a median keel; predorsal plate very rugose, short and crescent-shaped; premaxillary teeth villiform, forming a plate slightly curved; palatine teeth in two pairs of patches, an anterior subquadrate pair and a posterior elongated pair, the anterior one wider and continuous with the posterior patch; no gill-rakers on posterior (inner) face of the first and second branchial arches; total number of anterior gill-rakers: on 1st arch 17-22, on 2nd arch 18-23 (Ref. 3546, 7367, 57224, 81640). Dorsal and pectoral fins with a strong serrated, erectile spine; adipose fin well developed (Ref. 57224, 81640).
Body shape (shape guide): fusiform / normal; Cross section: circular.
Mainly marine but frequently found in brackish estuaries, sometimes enters freshwater (Ref. 3876). Frequent in lagoons (Ref. 7367). Common during winter (Ref. 2683). Feeds on fish, benthic invertebrates, zooplankton and detritus (Ref. 28587). Wide range of diet including a high percentage of penaeid and other prawns, crabs, polychaetes, fish and molluscs (Ref. 57352, 81640). Eggs very few, spherical, very large (16-17 mm diameter); males practise buccal incubation (Ref. 57224) during which it seems the species continues to feed (Ref. 81640). Ornamental and sometimes considered aquaria fish (Ref. 27121), the fish is venomous and can be dangerous to humans (Ref. 12484).
