Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm 22.2, range 17 - ? cm
Max length : 55.0 cm TL macho/indeterminado; (Ref. 6937); common length : 20.0 cm TL macho/indeterminado; (Ref. 3696)
Espinhos dorsais (total): 0; Raios dorsais moles (total): 10; Espinhos anais 0; Raios anais moles: 10. Dark markings on head and body; parallel bands on cheek. Pair of prominent spines projecting from in front of eyes suggests cow horns. Second pair of spines at lower rear corners of cuirass (Ref. 26938). Body deep, covered with hexagonal dermal plates (Ref. 37521).
Found in shallow water down to about 80 m, mainly in seagrass beds (Ref. 3696). Feeds on sessile invertebrates such as tunicates, gorgonians and anemones, as well as on slow-moving crustaceans, sponges (Ref. 3696), hermit crabs and marine plants (Ref. 13442). Oviparous (Ref. 205). Considered an excellent food fish; marketed fresh (Ref. 3696).
