FT. LAUDERDALE (CBSMiami) – Dozens and dozens of sharks were spotted just below the surface of the water off a private club in Hillsboro Beach.

Tuesday afternoon Chopper4 hovering above the Hillsboro Club, at 901 Hillsboro Mile, spotted the sharks less than 100 yards off the beach.

The sharks are on their annual migration. The marine predators, mostly black tip and spinner sharks, have been spotted from Jupiter to Ft. Lauderdale since the start of the month.

Several people wading in the water near the beach were unaware of the finned predators and a couple on a kayak seemed unconcerned as they paddled very close to the sharks as they headed to the shore.

A pair of men on paddleboards appeared to be equally unconcerned as they paddled out to where the sharks were and then back to shore.

Hillsboro Beach officials said since this was a private beach there were no city lifeguards to clear the water until the sharks had gone.

Earlier this month lifeguards on Deerfield Beach and several beaches in Palm Beach County closed their beaches due to migrating sharks. Once a shark appears near the shore, a lifeguard will close the beach and keep it closed until half-hour after the last shark is spotted.
