Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 15 - 16; Raggi anali molli: 19. This species included in the Enneapterygius flavoccipitis species complex is distinguished by the following characters: A 19; pectoral fin with 7 median branched rays; lateral-line scales 15-16 +19; mandibular-pore formula 4+1+4; eye diameter 100-119; preorbital 69-72; body depth 211-225; preanal-fin length 489-500. Colouration: preserved male with a black head-mask, posterior half of body dark, third dorsal fin pale (only basally dusky), anal fin plain black, no triangular black blotches above anal-fin base, pelvic fins pale, and caudal fin dark with a narrow pale margin (Ref. 131105).
Occurs on shallow waters, in a mixed coral, sponge and algae habitat exposed to waves and surge throughout the year. Its unusual rose and green body coloration is used as a camouflage in this kind of habitat. The body colors blend into the background (Ref. 131105).
