Here's a video that I chanced upon where an octopus was being attacked by a school of Leather Jackets.
I felt strange as to why the predator was the prey this time and even more baffled why this octopus was so passive and hardly retaliating. Old age perhaps?
Anyway, the moral of the story is in life is don't be too kuai lan because karma will be served to you one day and you will be whacked big time.
The other thought that was going through my mind was "Wow.... the octopus flesh is so white and juicy! Yummy!"
