Ökologie
seewasser bathydemersal; tiefenbereich 400 - 1600 m (Ref. 11953). Deep-water

Max length : 38.5 cm TL Männchen/unbestimmt; (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).
