					Maximum depth from Ref. 122885.  Maximum length for females from Ref. 106104.  Both max. lengths are based on occurrences (Refs. 106104, 114235); to be replaced with a better reference. Deep-sea species that inhabits bathyal mud bottoms (Ref. 106307).  Occurs on the deep middle (Ref. 105217) and lower slope where the species is abundant (Ref. 122885).  Recorded in the deep sea along with the  gorgonacean coral Isidella elongata (Ref. 122886).
