Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 68 - 622 m (Ref. 10482). Deep-water; 40°N - 4°S, 107°E - 150°W (Ref. 92340)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Pacific: Taiwan, Vietnam, Philippines, Indonesia, and Hawaii; northernmost record Emperor Seamounts. Apparently restricted to the North Pacific (temperate to tropical) and reports from New Zealand and New Caledonia are based on misidentifications.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 13.5 cm TL male/unsexed; (Ref. 28618); common length : 5.1 cm SL male/unsexed; (Ref. 10482)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 5. Lachrymal bone consisting of 2 spines over maxillary, first as a broad lobe, second as a broad spine pointing down; well marked suborbital ridge with 5 or 6 or more spines; second preopercle spine small or absent (Ref. 10482). Distinguished from other Hawaiian scorpionfishes by having only the anterior 4 or 5 tubed lateral line scales present, with the remainder of the lateral line absent; and presence of large melanophores on the caudal peduncle (Ref. 10482).

Biology     Glossary (e.g. epibenthic)

Benthic (Ref. 58302). Feeds on small fishes and crustaceans (Ref. 5755). Female specimens (4.70-5.59 cm SL) taken from the Emperor Seamounts have mature gonads filled with relatively large eggs of several developmental stages with the most developed eggs are ca. 0.4 mm in diameter (Ref. 92340).

Estimates based on models

Preferred temperature (Ref. 123201): 12.1 - 21.3, mean 16.2 °C (based on 121 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00696 - 0.04547), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
