Western Pacific: Australia. Records from other areas may represent different species, from Cocos-Keeling Islands throughout the East Indies; in the south from Bali eastwards to Samoa and New Caledonia and southward to Australia (Scott Reef and the southern Great Barrier Reef); in the north extending to the Yaeyama Islands of Japan and eastward to Micronesia (Palau, FSM - Truk and Enewetak, and the Marshall Islands).

Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 5 - 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 8 - 10; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 8 - 9. Characterized by semi-transparent body with red-brown internal bars; irregular reddish blotches on nape; presence of intense black spot above gill opening; three red blotches separated by white or yellow bars on side of belly; base of pectoral fin with narrow white band; longitudinal scale series 23-25; ctenoid scales, absent on head and breast; separated pelvic fins, thin membrane joining bases; depth of body 6.5-7.7 in SL (Ref. 90102). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).

Found on rocks of corals reefs in the infralittoral zone (Ref. 559, 48637). Solitary or in groups, resting at bottom (Ref 90102). Spawning appears to be repeated on a regular cycle, semilunar or every 14 days (Ref. 116739).

Estimates based on models

Preferred temperature (Ref. 115969): 25.4 - 28.9, mean 27.9 (based on 524 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Ελαστικότητα (Ref. 120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
