PORTSMOUTH, Va. (AP) - Another dying dolphin has been found in Virginia waters.
The dolphin was found Saturday morning in a creek near downtown Portsmouth. The Virginian-Pilot reports that the ailing animal had to be euthanized.
In a typical year, about 60 sick and dead dolphins wash up on Virginia's coastline. So far this year, 170 dead dolphins have been recorded in the Chesapeake Bay or along the Atlantic coast.
From New Jersey south to Virginia, more than 230 dolphin deaths have been reported. The National Oceanic and Atmospheric Administration has declared an unusual mortality event, which clears the way for an intensive scientific inquiry into what is causing the deaths.
No definitive conclusions have been reached, but many suspect a virus.
