HALIFAX—The recent deaths of four endangered North Atlantic right whales in the Gulf of St. Lawrence is alarming, given that the massive mammals are just arriving in Canadian waters for the season, a leading marine biologist said Wednesday.
Boris Worm, a biology professor and well-known whale expert at Dalhousie University in Halifax, said the sudden spate of deaths this month stands in contrast to last season, when there were no recorded deaths linked to ship strikes or entanglements.
