This species is recorded from depths of 18 m to at least 210 m, commonly at about 40-150 m depth, but may occur deeper; one specimen was taken by a trawler fishing in 123-277 m, but the depth of capture cannot be determined. Newly hatched young and egg capsule diameter unknown; egg diameter 1.7-1.9 mm (Ref. 72490).
