Etymology: Sebastes: Greek, sebastes = august, venerable (Ref. 45335); aurora: From the 'aurora' meaning dawn - referring to the colouring (Ref. 6885).
Eponymy: Aurora was the Roman goddess of the dawn. In the case of the goby, the name refers to the pattern on its caudal fin being ‘…reminiscent of the rising sun’. The name is often applied to species with pink/yellow colouration. (Ref. 128868), visit book page.

Head spines strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronals usually absent (Ref. 27437). Small lobes projecting from anterior part of upper jaw (Ref. 27437). Second anal fin spine long (Ref. 27437). Rose-red to pink dorsally, silvery on sides and ventrally (Ref. 27437).
