Huge schools of sharks have been gathering offshore in recent months as they make their annual migration north.
Blacktip and spinner sharks, among other species, have been seen from beaches along Singer Island and Palm Beach Shores.
They arrived in late December and are expected to hang around until April, Palm Beach County Ocean Rescue Capt. Julia Leo said.
“Their migration happens in the winter months, usually the same time that tourists are here,” she said. “We see them most often in January and February. They’re coming down and following their prey, which is either a mullet or Spanish mackerel.”
The sharks, which like to jump out of the water, typically ride the waves on the shore break, city of Riviera Beach lifeguard Eddie Green said.
He noted the sharks stay about 10 to 15 yards offshore and are visible daily.
“They’ve been here every day since December,” said Green, who was on duty Sunday at Ocean Reef Park. “They just like our beach for some reason.”
Beaches in the area have not been closed, though purple flags warning of dangerous marine life have been flying in the area.
No one has been bitten by a shark this year in Palm Beach County, though a 16-year-old Jensen Beach High School junior received 12 stitches to his right hand after being bitten by a blacktip reef shark Feb. 10 off Bathtub Beach.
In December, the waters off Jensen Beach were closed for a week after a suspected shark bite.
