Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 9 - 11; Anal spines: 3; Anal soft rays: 5 - 7. Swim bladder lacking or rudimentary; bones poorly ossified; spine weak and usually broken during capture; scales thin and deciduous, and white body musculature soft and flabby (Ref. 11015). Lateral line more or less a continuous trough covered by thin membranous scales, usually lost during capture (Ref. 10482). Body is black in small specimens; maroon and black in adults (Ref. 11015). Buccal cavity black with patches of bright orange and red in life; pharyngeal teeth red or orange (Ref. 11015).

Among all scorpionfishes, it is structurally best adapted for mid-water existence (Ref. 11015). Benthopelagic (Ref. 58302). Feeds mainly on crustaceans, amphipods and sergestid shrimps (Ref. 28023). Anterolateral glandular grooves with venom gland at least in anal-fin spines (Ref. 57406).

Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 10.7, mean 7.1 °C (based on 831 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7578 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00417 - 0.02629), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): Unknown.
