Unique interactions between leviathans

My friend and I lured the Collector Leviathan close to the Shiver Leviathans in game to see if they would interact or acknowledge each other - unfortunately not! It would be neat if Leviathans had a unique interaction of some sort - a sound/attack each other/flee from each other etc. especially when players makes the effort of luring them to each other. It would be a neat little easter egg!
