Ecology of Illex coindetii

Main Ref.	Schneider, W., 1990
Remarks	Neritic, oceanic (Ref. 91956). Inhabits muddy, sandy and detritic bottoms covered with Funiculina spp. (Ref. 2453) in middle and lower sub-littoral and upper bathyal zones in temperate latitudes. In general, juveniles and adults share the same depth range throughout the year; many large individuals can be found in deeper waters (Ref. 64257). Performs diel vertical movements (Ref. 275) as well as seasonal migrations (Ref. 64257). Opportunistic predator (Ref. 2450, 64257), feeding on the most abundant prey available, even consuming tunicates (Ref. 64257). Mainly feeds on fish, crustaceans and cephalopods (Refs. 2450, 64257). Comes very close to the seabed but was observed to mainly feed on prey swimming off the bottom (Ref. 64257). Exhibits cannibalism (Ref. 2482).
