The species undergoes diurnal vertical migration, where they are found at lower depths during the day and migrate up the water column at night. [11] In a study about vertical distributions of pelagic cephalopods conducted by Clyde Roper and Richard Young, it was found that, during the day, most H. heteropsis specimens were found at 500–700 ...
