Found on the outer continental shelf and upper slope on rough, rocky bottom. Water temperature: 8.5-11.3°C. Food habits unknown. Oviparous. Not utilized at present. Found in waters 75-550 m deep (Ref. 26938). Lives at depths off 36-230m in the northern portion of its range, and in waters deeper than 460m in its southern range (Ref. 55294). Maximum depth reported taken from Ref. 55584.

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). During courtship and prior to copulation, the male bites and wraps female pectoral fin body, tail and gills (Ref. 49562, 51128).
