					Minimum depth from Ref. 8. Benthopelagic (Ref. 105772).  Mesopelagic (Ref. 122930).  Known from pelagic depths between 100 to 200 m (Ref. 92299).  Abundant on the upper slope (Ref. 105772).  Associated with the gorgonacean coral Isidella elongata (Ref. 122886).  Found on seamounts (Ref. 122931).  Carries out diel vertical migrations.  Diet is based on pelagic crustaceans like euphausiids and calanoids, and bottom feeding has been reported to be minimal, as is the passive ingestion of forams.  However, at night, large specimens feed near the bottom on suprabenthic gammarid amphipods.  In general, predatory activity occurs higher in the water column at night (Ref. 105773).

					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the order Decapoda are mostly gonochoric.  Mating behavior:  Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
