Bigeye jacks form the iconic "tornado" schools that Cabo Pulmo is famous for: tens of thousands of individuals rotate in a tight column that can be 10 m wide and stretch from the bottom to the surface. The school behavior is a predator-confusion defense mechanism and the sheer scale of the aggregation at Cabo Pulmo — possible only because the reef is so productive — is one of the most visually arresting spectacles in the eastern Pacific.
