Two additional dolphins washed up on New Jersey beaches Saturday, including one in Brigantine, bringing the statewide total to 68 since July.

Dolphin carcasses were reported in Sea Girt, Monmouth County, and off Brigantine's 43rd Street beach, according to the Brigantine-based Marine Mammal Stranding Center.

The deaths have been declared an "unusual mortality event" by the National Oceanic and Atmospheric Administration due to the significant number of dolphins found between New York and Virginia.

Although officials have said the dolphins appear to be dying from viral pneumonia, a precise cause is still unknown.
