Ecology of Pasiphaea sivado
Main Ref. Williams, A.B., L.G. Abele, D.L. Felder, H.H. Hobbs Jr., R.B. Manning, P.A. McLaughlin and I. Pérez Farfante, 1988
Remarks 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).
