簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 13; 背的軟條 (總數): 12-14; 臀棘 3; 臀鰭軟條: 5 - 8. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Eye large; 2 strong, sharp, hooked spines on lower margin of suborbital bone; 2nd anal fin spine longer than 3rd in depressed fin (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pinkish red to yellowish red, silvery ventrally; dusky saddles on back, may be vague; green streaks on caudal fin (Ref. 27437).
頭部棘強的到中等的 - 鼻骨， preocular, 眶後的﹐鼓皮似的與腔壁的棘呈現, nuchals 通常不存在, 眶上的與冠棘不存在.(參考文獻 27437) 眼大的; 在眶下骨的下緣上的 2根硬且利又鉤狀的棘; 第二根臀鰭棘長度超過第三在扁平的鰭.(參考文獻 27437) 尾鰭一般切割成鋸齒狀。 (參考文獻 6885) 略帶桃色的紅色到淡黃色的紅色, 銀色的腹地; 暗色的鞍狀斑背面, 可能是模糊的; 在尾鰭上的綠色的條紋.(參考文獻 27437)
Mostly found in offshore water on soft bottoms (Ref. 2850). Ovoviviparous (Ref. 6885). Anterolateral glandular grooves with venom gland (Ref. 57406). Commonly caught with trawls but usually discarded because of its small size (Ref. 2850). Rarely taken on baited hook in deep water (Ref. 2850).
大部份在軟質底部上發現於外海水域了。 (參考文獻 2850) 卵胎生的.(參考文獻 6885) 通常用拖網捕獲了但是通常丟棄了由於它的體型小.(參考文獻 2850) 在深水中很少採自了有誘餌的魚鉤。 (參考文獻 2850)
