The Navesink & Shrewsbury Rivers are full of cow nosed rays! This is likely why Bull Sharks have been sighted. The rays are abundant this year. As early as three weeks ago I spotted them at Allenhurst Beach.
Cow Nose Rays Invade Navesink

The New Jersey Shark Attack file was established in 1998 to investigate all possible incidents of shark attack within the waters of New Jersey. Due to the close proximity and similar habitat with Long Island the file was expanded in 2017 to include all attacks in New York waters. The current area of study is the New York Bight that runs from Cape May, New Jersey to Montauk, New York. Rivers, bays, and estuaries from the areas are included in the reporting area. Also included are freshwater bodies of water and aquariums. The purpose of the file is to place all available data on shark attacks in one useful form to demonstrate how rare these events are. The ultimate goal of the file is to encourage shark conservation as humans pose a much greater danger to sharks than they do to us. A second goal of NJSAF is to investigate and expose those that sell and profit from the illegal shark fin trade.
