Max length : 85.0 cm TL самец/пол неопределен; (Ref. 33115); common length : 40.0 cm TL самец/пол неопределен; (Ref. 2683)
колючие лучи спинного плавника (общее число): 1; членистые (мягкие) лучи спинного плавника (общее число): 7; колючие лучи анального плавника 0; членистые (мягкие) лучи анального плавника: 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 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). Dorsal and pectoral fins with a strong serrated, erectile spine; adipose fin well developed (Ref. 57224).
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). Eggs very
few, spherical, very large (16-17 mm diameter); males practise buccal incubation (Ref. 57224). Ornamental and sometimes considered aquaria fish (Ref. 27121), the fish is venomous and can be dangerous to humans (Ref. 12484).
