Federal authorities said the second critically endangered North Atlantic right whale found dead in the last month showed injuries consistent with a collision with a ship.
The whales number less than 360 and they have experienced decline in recent years. The National Oceanic and Atmospheric Administration said it was notified of a dead right whale floating off Savannah, Georgia, on Feb. 13.
The agency said late Friday that a necropsy of the animal “found evidence of blunt force trauma including fractures of the skull” and that those “injuries are consistent with a vessel strike prior to death.” The announcement came just days after NOAA released more details about a dead right whale off Massachusetts that showed signs of entanglement in fishing gear, which is the other major threat the animals face.
The back-to-back deaths of the rare whales that both showed evidence of the species’ two major threats should motivate rule changes, numerous environmental groups said Saturday. The groups have long pushed for stricter rules governing shipping and commercial fishing to help protect the whales.
