头部棘非常强的 - 鼻骨， preocular, 眶上的，眶后的，和鼓皮似的，腔壁的与颈背的棘呈现,冠棘不存在; 大的头部与细长的身体; 在头部上的强的刺状脊; 第三个背棘不是远长过第二, 第 4 或第 5; 在胸鳍上的强的凹槽.(参考文献 27437) 鲜红色在鳍上有一些黑色; 鳃室大部份灰白.(参考文献 27437) 尾部的略圆.(参考文献 6885)
Very common on soft bottoms (Ref. 2850). Oviparous (Ref. 205). Eggs are extruded in floating gelatinous masses (Ref. 31279). Have a thick glandular tissue on posterior margin of fin spines which is believed to be venomous (Ref. 57406). Rarely taken by game fishers (Ref. 27436). Flesh sweeter than that of other rockfishes (Ref. 27436).
非常常见于软质底部.(参考文献 2850) 卵生的.(参考文献 205) 卵在漂浮的凝胶团被释出。 (参考文献 31279) 有一个在鳍棘的后缘上的厚腺组织是相信是有毒的.(参考文献 57406) 很少采自了钓客。 (参考文献 27436) 其他礁石鱼类的比那甜的肉.(参考文献 27436)
Unlike other representatives of this group, this species has internal fertilization Oviparous (Ref. 6885). Females possess specialized ovarian structures including stalk-like ovigerous lamellae and secretory epithelia (Ref. 32832).北太平洋: 鄂霍次克海北至白令海的拿瓦倫峽谷而且從僵局岸堤，而且在阿留申群島的 Ulm 高地向東南到塞德羅斯島，墨西哥的下加利福尼亞。 記錄來自日本了。 (參考文獻 559)
