Etymology: Synodus: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335). More on author: Lacepède.
Environment: milieu / climate zone / depth range / distribution range
; 海 関連する礁; 深さの範囲 3 - 121 m (Ref. 58302), usually 5 - 60 m (Ref. 37816). Tropical; 30°N - 45°S
Indo-Pacific: Red Sea and East Africa to the Hawaiian, Line, Marquesan, and Ducie islands, north to the Ryukyu Islands, south to the Lord Howe, Kermadec and Rapa islands (Ref. 1602). Reported from New Zealand (Ref. 5755) and Persian Gulf (Ref. 68964).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 14.0  range ? - ? cm
Max length : 40.0 cm TL オス/雌雄の選別がない; (Ref. 637); common length : 30.0 cm TL オス/雌雄の選別がない; (Ref. 637)
背面の脊椎 (合計): 0; 背鰭 (合計): 10-14; 肛門の骨 0; 臀鰭: 8 - 10. Adults variable from grey to red (Ref. 48635). On some individuals, the hourglass- or saddle-shaped markings along its side may be obliterated by an almost solid dark red band (Ref. 1602). Large individuals are often thick-bodied, giving a hump-backed appearance (Ref. 1602).
Inhabits deep lagoon and seaward reefs to depths over 40 m (Ref. 9710); sometimes found on sandy bottoms concealing itself in the sand. Prefers to rest on hard surfaces and frequently occurs in pairs (Ref. 37816). Benthic (Ref. 58302). Feeds on small fishes by seizing these from passing schools, also shrimps (Ref. 89972). Caught with various types of artisanal gear; sold fresh or dried salted in markets. Minimum depth reported taken from Ref. 30874.
