Aerial footage released on Monday showed the waters off the coast of Israel's northern town of Hadera swarming with sharks.
Some 150 bull and sandbar sharks have migrated to the Hadera River estuary, where the waters are heated by emissions from a nearby power station, to eat minnows and crustaceans that live in the environs, according to Channel 2.
Drones captured footage of the sharks on Sunday who arrived as they do each year during breeding season.
