Etymology: Gobiodon:Latin, gobius = gudgeon + Greek, odous = teeth (Ref. 45335); bilineatus:Named for its two distinct, bright blue lines through the eye, the remaining distinct colour pattern that remains in the largest adults when alive; from Latin words 'bi' for two and 'linea' for line.

Espinhos dorsais (total) : 6; Raios dorsais (total) : 10 - 11; Espinhos anais: 1; Raios anais : 8; Vértebras: 26. This species is distinguished by the following characters: D VI+I,10-11; A I,8-9 (usually 9); head and body naked; body slightly compressed and relatively elongate (body depth at pelvic-fin origin 36-40% SL), dorso-ventrally symmetrical; distance between D1 insertion and dorsal insertion of pectoral-fin 53-71% of head length; rounded head with upper lip curved; small mouth, upper jaw extending to anterior margin of the eye; groove between isthmus and interopercle absent; caudal peduncle deep (minimal depth 16.3-17.9% SL); caudal fin relatively short (21.7-23.2% SL). Colour of juveniles and subadults light greenish or reddish with 5 vertical blue lines on head while adults are usually uniformly orange-red or dark red, sometimes with remnants of lines on the head but always with 2 distinct bluish lines through the eyes, sometimes extending ventrally to suborbital area; dorsal and anal fin usually with a narrow light bluish band along bases, fading with growth (Ref. 94082). Body shape (shape guide): short and / or deep; Cross section: compressed.
Facultative air-breathing in the genus (Ref. 126274); Usually occupies the reef slope and fore reef areas and often in large colonies of Acropora samoensis but also present in Acropora secale and A. gemmifera in northern Red Sea (Ref. 94082).
