Fluke

"Edward Grant, 45, of the Leonardo section of Middletown caught the strangely shaped fish in Raritan Bay... Grant tossed the 18.5 inch fluke back into the bay, deciding it had been through enough already and deserved to live.

"I felt bad for it," he said. He surmised a large bluefish or small shark had previously attacked the fluke, which was completely healed from whatever injuries it had suffered."
