分布於臺灣至日本南方，屬於分布緯度較北之魚種。臺灣發現於北部、東北部、南部、小琉球、蘭嶼及綠島等海域。陳等(2010)首次紀錄於墾丁地區。

一般以一支釣及延繩釣的方法捕獲。魚肉白，但質地較爛，煮湯時肉易散開且多溶解油質，因此適合抹鹽油煎食用。唯須注意其內臟可能累積熱帶海魚毒。而它的鱗片及棘刺尖利，需小心刺傷。在水族館中也有人看上它鮮紅的體色，將它飼養做為觀賞魚。

體呈橢圓形，中等側扁。頭部具黏液囊，外露骨骼多有脊紋。眼大。口端位，裂斜。下頜不突出於上頜。前上頜骨的凹槽大約不達眼窩前緣的垂直線上；鼻骨的前緣圓形，後端具小棘；鼻窩通常沒有小刺(有些標本則有)。前鰓蓋骨後下角具ㄧ強棘；眶下骨上緣鋸齒狀。體被大型櫛鱗；側線完全，側線鱗數 35-38，側線至背鰭硬棘中間點之鱗片數 2.5；頰上具 5 列斜鱗。鰓耙數5-8+10-11=15-19。背鰭連續，單一，硬棘部及軟條部間具深凹，具硬棘 X-I，軟條13；最後一根硬棘短於前一根硬棘。臀鰭有硬棘 IV，軟條8- 9(9)；胸鰭軟條 13-15 (14)；尾鰭深叉形。體側扁長卵形，側線鱗數35～38，上枝鰓耙數5～8，下枝鰓耙數10～11，鼻骨有數枝小棘。體色近於紅色，體側有9～10條銀白色縱帶；在紅色的頭部上沿著前鰓蓋骨的後緣有一條白色的橫帶。背鰭鰭膜紅色；各鰭橙紅色；鰓部及腹部銀白。

主要棲息於深水域的岩石區。白天獨自躲在洞穴或裂縫中休息，或徘徊在家門附近的暗礁之外，夜晚則出外覓食，以蝦蟹之類的甲殼動物或小魚為主要食物。
