A 5-foot blacktip shark was found in a Florida condominium complex swimming pool last week in what seemed to be part of a cruel prank.

The shark was listless when it was discovered by Nicole Bonk and her husband in a Mariner’s Cay complex in Hypoluxo, in Palm Beach County.

The couple carried the shark to the nearby Intracoastal Waterway and pulled it gently by the tail once it was in the water in an attempt to flush the chlorinated water from its system.

This was soon after Bonk had spotted two boys dumping the shark into the pool at about 11 p.m. The shark had hooks in its mouth, implying a recent capture by anglers.

“We tried to revive him, but he most likely did not live,” Bonk told the Sun-Sentinel. “He was barely moving after the trauma. We did our best to try to save this creature.”

The Florida Fish and Wildlife Conservation Commission is investigating the incident, and it’s hoped that security cameras around the pool will help officers identify the boys.

Said Bonk, “They left the shark in the pool to die. I think they’re terrible children because it’s animal cruelty.”

Blacktip sharks, named because of the distinct markings at the ends of their fins, are found in tropical and subtropical waters around the world.

They can measure to about 7 feet and feed largely on schooling fish such as mullet, herring, anchovies and sardines.

Blacktip sharks have been known to attack swimmers and surfers off Florida, mostly inflicting bites to hands and feet as they forage on bait fish in the shallows.

The species is listed as “near-threatened” by the International Union for the Conservation of Nature (IUCN), and as “vulnerable” in the Northwest Atlantic.
