分布於印度-太平洋區，由紅海、南非到馬歇爾群島和薩摩亞，北至日本琉球與台灣海域等。台灣各地海域皆有分布。

中小型之隆頭魚，雖然肉質好，且具有膠黏性，非常適合紅燒，但是因為產量不多，所以並不具有經濟價值，只偶爾出現在漁市場和水族館。漁法主要為手釣及底延繩釣。

體長型；頭部背面輪廓幾成直線。上下頜突出，前側各具 4犬齒，上頜兩側各具 1大圓犬齒。頰部與鰓蓋被鱗，側線平滑連續。D. XII, 9-10；A. III, 10-12； P. 16；L.l. 31-32；G.R. 5-10；尾鰭稍圓，上下鰭條延長。幼魚體呈褐色而散佈許多白色橢圓班；背鰭之前及後端、臀鰭中央及後端、胸鰭基部、腹鰭及尾鰭基部中央皆具一眼班。成魚頭部體紅褐色，體側淡黃色，背部偏紅，腹部較淡；體背後部與尾柄上半部具小黑點；背鰭下方具 3-4個成一列的白點；奇鰭紅色；腹鰭幾乎全為黑色；臀鰭中央具一大黑斑，末端基部具一小黑點；尾鰭基部中央有一黑點。

主要棲息於水深10到20公尺處的礁岩海域，尤其是礁岩向海面珊瑚繁茂的區域，但分布的深度範圍很廣，可以從水深5公尺到水深100公尺。棲所環境和腋斑狐鯛相似。幼魚時常躲在黑色珊瑚和柳珊瑚附近，也常躲在穴頂下方，常客串魚醫生為其它魚清除身上的寄生蟲。成魚專門吃岩石縫下的甲殼類和貝類，夜晚則躲在岩石下面或洞穴裏睡覺。

Diana's hogfish, Bodianus diana, is a species of wrasse native to the Indian Ocean from the African coast to the Nicobars and the Cocos-Keeling Islands. Reports of its presence in the western Pacific Ocean are erroneous. It occurs on the seaward side of reefs at depths from 6 to 50 m (20 to 164 ft) (though rarely deeper than 25 m (82 ft)). It can reach a length of 16.9 cm (6.7 in). This species is of minor importance to local commercial fisheries and is found in the aquarium trade.

Found in coral rich areas of seaward reefs (Ref. 5213). Juveniles often shelter near black corals and gorgonians; also frequent cave ceilings (Ref. 8631). Feeds mainly on benthic invertebrates such as molluscs and crustaceans.
