A group of great white sharks was spotted off the U.S. coast, close enough to pose as a threat to the local population, Utah People's Post reports. 

This is an uncommon sighting, as white sharks do not swim this close to the shore and are also not commonly seen in those regions.

According to Mary Jane Schramm from the Gulf of Farallones National Marine Sanctuary, two coast guards helicopters flying 500 feet above the waters off of Northern California's coast on October 16^th spotted a cluster of 20 great white sharks swimming around through the waters.

The sighting was considered odd as these fully mature sharks often swim from the ocean toward the Farallon Islands, Año Nuevo, and Drakes Bay this time of the year. They travel from within the colder parts in order to feed.

The sharks could pose as a danger not only to the seal population, but also to humans, such as beach goers or wind surfers.

This species of white sharks are typically found along the coast of Australia, South Africa, and parts of the United States.

The Census for Marine Life has reported that there are currently 3,500 great white sharks left in the world, with around 220 of them inhabiting the waters around the central Californian coast.
