Short description
Identification keys | Morphology | Morphometrics
Has a distinctive blue-white line below the eye that usually continues over the axil to above the anus on the body, bordered by a bright orange one below over the gill section. Head deep blue, continuing and gradually changing on the body to bright orange on the tail (Ref. 48636).
Body shape (shape guide): elongated.
Adults inhabit seaward and sheltered reefs (Ref. 90102). They occur in coral rich habitats at about 10 m depth, usually among Acropora branches (Ref. 48636). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
