More Info
|
Distribution |
Great Barrier Reef, Queensland. Elsewhere the species is known from Japan (southern Kyushu to Ryukyu Islands), Papua New Guinea (Kimbe Bay), and possibly the Maldives. Adult pairs live within the the branches of Acropora corals, while juveniles are solitarily on coral edges. |
|
Features |
Dorsal fin VI-I, 9-11; Anal fin I, 8-9; Pectoral fin 19-21; Vertebrae 26. Body depth at pelvic-fin origin 32.4-40.8% of standard length; distance between first dorsal-fin origin to dorsal-most point of pectoral-fin base 50.4-64.8% of head length (HL); pectoral fin relatively long, its length 90.6-112.5% of HL; groove between isthmus and interopercle absent. |
|
Etymology |
The specific name is from the Latin spadix (= reddish-brown), in reference to the ground coloration of head and body. |
