Ecology of Alloteuthis media

Main Ref.	Templado, J. and R. Villanueva, 2010
Remarks	Also found in brackish water. Demersal (Ref. 122892). Commonly found on the continental shelf and the upper slope (Ref. 104424), where it is the abundant in the former. Most common in water >150 m deep over sandy and muddy grounds. Undertakes seasonal migrations between offshore (in winter) and inshore (in spring) areas (Ref. 122892). Typically associated with the deep-sea gorgonacean coral Isidella elongata (Ref. 122886).
