Eastern Central Pacific: Hawaiian Islands, off Baja California, and the Revillagigedo Island. Probably more widely distributed.
中太平洋東部: 夏威夷群島,外海的下加利福尼亞, 與雷維拉吉哥多島。 可能更廣泛分佈了。

生物学特性     字汇 (例如 epibenthic)

Occur mostly at depths of 100 m or more and has been captured at night at relatively shallow depths (9-46 m). More common around islands (records from the continental coasts are rare) (Ref. 9335). Inhabit rocky bottoms but many specimens have been trawled from relatively open waters in Hawaii (Ref. 5403). Benthopelagic (Ref. 58302). Gonads of specimens collected in Hawaii in November appear to be near spawning condition (Ref. 5403).

大部份生存深度 100个公尺或更多而且已经在相当浅的深度被捕获在晚上。 (9-46 公尺) 更普遍岛 (来自大陆沿岸是稀有的的纪录) 的周围.(参考文献 9335) 栖息于岩石底部,但是许多标本曾经在夏威夷以拖网捕获自相当开放的水域。 在十一月在夏威夷被收集的标本的生殖腺似乎接近产卵状况。

Estimates based on models

Preferred temperature (Ref. 123201): 15.5 - 22.6, mean 20.8 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00740 - 0.03896), b=2.91 (2.72 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  4.2   ±0.73 se; based on food items.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
