The National Marine Fisheries Service said in a news release Sunday the dead adult whale was spotted off the coast of Myrtle Beach. 

The agency said the same right whale had been entangled in ropes from fishing gear at least since October, when it was sighted swimming with fishing line extending from its mouth past its tail. The whale was spotted again in February off Florida and a team of experts was dispatched, but was unable to free the ropes.

Fewer than 400 North Atlantic right whales are believed to survive. The fisheries service said 34 right whales have been confirmed dead in the U.S. and Canada since 2017.
