What was not the surprise of these employees of an oil platform when they looked down into the sea... Hundreds of sharks encircled their platform swimming on the surface of the water. This scene was filmed by one of the employees about forty kilometres off the coast of Grand Isle, Louisiana
Impressive, it is not for all that surreal since this migratory phenomenon is common in this region. The sharks, which had migrated to the south for the winter, are back in the north to spend the summer
