Etymology: Opistognathus:Greek, opisthe = behind + Greek, gnathos = jaw (Ref. 45335); to the very elongate upper jaw of the type species of the genus, Opistognathus nigromarginatus (Ref. 128653); dendriticus:Name from Greek 'dendron' for tree, referring to the tree-like, branching pattern of the cephalic pores.

Ambiente: milieu / zona climática / intervalo de profundidade / gama de distribuição Ecologia
marinhas associadas(os) a recifes; intervalo de profundidade 2 - 40 m (Ref. 90102). Tropical
Espinhos dorsais (total) : 10 - 11; Raios dorsais moles (total) : 13 - 14; Espinhos anais: 2; Raios anais moles: 11 - 13; Vértebras: 26 - 27. This species is distinguished by the following characters: a rigid upper jaw lacking flexible lamina posteriorly, extending about 0.6-0.9 eye diameters behind posterior margin of orbit; infraorbitals are relatively slender and tubular, the third infraorbital with moderate lateral opening and wide suborbital shelf; D X-XI,13-14; A II,11-13; scale rows in horizontal series 66-95; vertebrae 10-11 (usually 11) + 16-17. Colouration: dorsum with 6-7 dark blotches along base of dorsal fin, sides with a double row of large pale spots, and spinous dorsal fin with a single black spot between spines 3 to 5-7 (Ref. 128653). Cross section: compressed.
Mouthbrooders. Eggs which are clumped together in a sticky ball get incubated inside the parent's mouth (Ref. 40511).
