In short: Witness the arrival of a billion Indian oil sardines. This massive biological event, driven by the Indian monsoon, creates a spectacle so vast it can confuse predators.

The Indian monsoon creates an oceanic vacuum that brings immense wealth of life to the region. This phenomenon leads to the arrival of massive schools of Indian oil sardines, which can amass to over three miles in length.
