This would be a good idea…if the giant ball of fish WENT somewhere!
Mackerel perform a natural defense mechanism called a bait ball. Giant schools of mackerel rush together and swim in a giant circle.
The idea behind to move is to ward off predators with the massive size of the fish ball.
Unfortunately for the mackerel, tuna and dolphins don't really care!
The tuna and dolphins swarm on the mackerel and pick the ball apart. The ball is so huge that even BIRDS swim down to grab a few bites.
Poor mackerel…that's nature we guess!
Watch (above) as the fish try to protect themselves from becoming dinner!
