Several beaches on long island in the US have been closed after a number of shark sightings.
This is reported by the Weather Channel.
This year, several different species of sharks have been recorded on long island that was not there before.
During the week, at least 9 sharks were seen off the coast of Nassau County. The invasion of predators occurred a few days after the death of a woman in a shark attack off the coast of Maine.
Sharks have appeared in this area before, but they have never swum so close to the shore. Helicopters and police boats patrol the beaches.
