Size / Vikt / Age
Könsmognad: Lm ? range ? - ? cm
Max length : 18.0 cm SL hane/ej könsbestämd; (Ref. 559); common length : 10.0 cm TL hane/ej könsbestämd; (Ref. 4510)
Taggstrålar i ryggfenan (totalt) : 11 - 12; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 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).
Body shape (shape guide): fusiform / normal.
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).
