Shoaling Memes

Nothing unites mortal enemies like a buffet of easy prey! Marine predators spend most of their time fighting over territory and resources, but introduce a sardine shoal and suddenly they're the most civilized creatures in the ocean. It's like watching politicians who've been at each other's throats suddenly cooperate when there's funding to distribute. Nature's version of "the enemy of my enemy is my friend" except in this case, the enemy is delicious and swimming in convenient, bite-sized packages. Evolution really outdid itself with this diplomatic solution to predator conflict resolution.
