簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 10; 背的軟條 (總數): 9; 臀棘 3; 臀鰭軟條: 8. This species is distinguished by the following characters: body moderately deep, its depth 2.4-2.8 times in standard length; head length 0.9-1 times in body depth, 2.5-2.9 times in SL, dorsal profile near eye slightly convex; snout moderately long, its length about 1.7-2.4 times in HL, measured without the lip the snout is 0.9-1 times in cheek height, its dorsal profile slightly concave, snout angle relative to upper jaw between 50° and 65°; interorbital space convex to flat; posterior nostril an oblong longitudinal opening, closer to orbit than anterior nostril; eye situated close to dorsal profile, its length 3.4-5.4 times in HL; cheek moderately high, its height 2.0-2.9 times in HL; lateral teeth in jaws conical; outer surface of maxilla smooth or with a longitudinal ridge; D X,9 with the 3rd dorsal-fin spine usually longest, its length 2.3-2.9 times in body depth; A III,8 with the 1st or 2nd soft ray usually the longest, its length almost equal to or slightly longer than length of base of soft-rayed portion of anal fin and 1.3-1.4 times in length of entire anal-fin base; pectoral-fin rays 13; pelvic-fin membranes between rays closest to body usually with dense melanophores; no scales on cheek; 46-48 lateral-line scales; 4½ scale rows between lateral line and base of middle dorsal-fin spines; 15 to 17 scale rows in transverse series between origin of anal fin and lateral line; usually 15 rows in lower series of scales around caudal peduncle; 2-7 scales in supratemporal patch; inner surface of pectoral fins partially or densely covered with scales; posterior angle of operculum fully scaly. Colour of body silvery, tan, or yellowish, base of scales often black, often a series of 8-9 dark bars (may be absent in some individuals); base of pectoral fins red; sometimes a red streak originating on upper operculum, passing beneath eye and onto snout; 2 red spots often on upper rim of eye; lips reddish; fins pale or reddish, sometimes brilliant red on membranes near base of pelvic fins, and between spinous rays of dorsal and anal fin (Ref 68703).
吻中等長度的。 頰沒有鱗片。 身體銀色的﹐黃褐色的或淡黃色的顏色, 時常有一系列的 8 或 9條深色的橫帶。 縱帶可能是一些個體沒有。 胸鰭基底紅色。 偶然地一個紅色的條紋存在, 在上面的鰓蓋上開始, 在眼之下經過與對吻部之上。 淡紅的唇。 鰭灰白或淡紅的, 有時在腹鰭的基底附近的在薄膜上的色彩豔麗的紅色與在刺狀鰭條之間背部的與臀鰭。 鱗片的基底時常黑色的。

生物學特性     字彙 (例如 epibenthic)

Adults inhabit coral reefs during daytime where they feed occasionally in sand and rubble areas between coral heads. At night, they move out over the sandy sea floor and forage actively. Usually occur in small schools. Juveniles live in shallow, inshore waters such as seagrass and mangrove areas, moving into deeper water as they age (Ref. 27260, 28202). Feed mainly on crustaceans, echinoderms, mollusks and fish, with crabs and sea urchins predominating. Much of the information reported for this species was based on misidentifications and referred to L. olivaceous (see Ref. 2295). Marketed fresh or frozen (Ref. 9987). Caught primarily by handline. One of the favourite food and sport fishes around the Great Barrier Reef. A major food fish in New Caledonia. Occasionally implicated in cases of fish poisoning (ciguatoxin) (Ref. 68703).

棲息於珊瑚礁在白天期間在那裡它們吃偶見於在珊瑚頂部之間的沙子與碎石區。 在晚上,他們移出到沙的海洋底部上而且覓食活躍地。 通常形成小群魚群。 主要捕食甲殼動物,棘皮動物, 軟體動物與魚,與螃蟹與海膽成為主流。 許多訊息這個種的報告是以誤鑑為依據而且指的是 L. 橄欖色的 .(見參考文獻 2295) 生鮮或冷凍地在市場上銷售。 (參考文獻 9987)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

L. miniatus are serial hermaphrodites with a protogynous strategy (i.e, female first, male second). Sexual bimodality was present in both age and length frequency distributions (Brown et al 1994). Juveniles live in shallow, inshore waters such as seagrass and mangrove areas, moving into deeper water as they age (Ref. 27260, 28202). Also Ref. 103751.西太平洋: 澳洲北部 (包括西澳大利亞) ,新加勒多尼亞, 與琉球群島。 在分佈的範圍外邊的發生記錄可能指的是 尖吻裸頰鯛〔Lethrinus olivaceus〕
