Typically found in water with a depth of 0 to -3,130 meters (0 to -10,269 feet).Mean = -756.260 meters (-2,481.168 feet), Standard Deviation = 1,099.580 based on 54 observations. Ocean depth information for each observation from British Oceanographic Data Centre.

Biome: Saltwater . Demersal .

Reproduction

Oviparous (Ref. 205). Eggs are extruded in floating gelatinous masses (Ref. 52092).
