A third endangered whale has been spotted entangled in fishing gear off the East Coast, marking an alarming end to the year for a species threatened with extinction.
The whales are North Atlantic right whales, which number fewer than 400 and are vulnerable to ship collisions and entanglement in gear. The National Oceanic and Atmospheric Administration said an aerial survey found an entangled whale about 60 miles (96 kilometers) east of the Outer Banks of North Carolina on Dec. 16.
