Great whites visit Cape Cod beaches – Shark specialist Greg Skomal on why more sharks are making their way north

Swimmers in Cape Cod are on high alert this week after a pair of great white sharks were seen swimming just off shore. This comes one week after three other sharks were spotted in the same area, marking the first official shark sightings of the summer.

Beaches have not been officially closed, but the local harbormaster has issued a warning telling swimmers to stay away from the area's seals, which are known to be a favorite snack for the white sharks.

Shark specialist Greg Skomal explains to Ashleigh on "Early Start" this morning why more sharks are making their way to northern beaches during the summer.
