The species' depth distribution is less clear, with different authors citing depths of 350–900 metres (1,150–2,950 ft), 300–2,000 metres (980–6,560 ft), 450–2,000 metres (1,480–6,560 ft), 77–2,055 metres (253–6,742 ft), and 600–1,400 metres (2,000–4,600 ft). It is reported to

be most abundant at depths of 750 metres (2,460 ft), 500–1,000 metres (1,600–3,300 ft), or 900–1,300 metres (3,000–4,300 ft). There are known to be both seasonal and geographical variations in depth, which may help to explain the variation.
