Two endangered whales have been spotted entangled in fishing gear off Massachusetts, and one is likely to die from its injuries, the federal government said.
They are North Atlantic right whales, which number less than 400 and face existential threats from entanglement in gear and collisions with ships. An aerial survey found the whales swimming about 50 miles southeast of Nantucket on Dec. 9, the National Oceanic and Atmospheric Administration said.
