US probes spike in dolphin deaths off East Coast
WASHINGTON (AFP) - More than 124 bottlenose dolphins have washed up along the Atlantic coast since July, a startling number that has prompted US officials to launch an investigation into the mysterious deaths.
Scientists are working to find out if an infectious pathogen may be to blame since some of the dolphins appeared to have lesions in their lungs.
An "unusual mortality event" has been declared due to the "unexpected and significant die-off" that has spanned the coasts of New York, New Jersey, Delaware, Maryland and Virginia since early July, said the National Oceanic and Atmospheric Administration's (NOAA) Fisheries unit.
Eighty-nine were found in July and another 35 have washed up so far this month.
