морской батидемерсальный; пределы глубины 400 - 1600 m (Ref. 11953). Deep-water

Maturity: Lm ?  range ? - ? cm
Max length : 38.5 cm TL самец/пол неопределен; (Ref. 11953)
Although most captures have been made with bottom trawls, specimens have recently been taken in midwater trawls fished close to the bottom, suggesting forays to the water column by individuals of different sizes (Ref. 11953).

Estimates based on models
Preferred temperature (Ref.
