On Saturday, an endangered 44-foot Sei whale was found dead in the East River at the Port of Brooklyn, likely struck by a 19-deck cruise ship. Despite being protected internationally, vessel strikes pose a significant threat to the dwindling population of Sei whales. The exact cause of the collision remains unknown, but experts believe the interaction with the ship contributed to the whale’s death. The increasing presence of whales in New York waters has led to calls for boaters to exercise caution and for ship captains to reduce speed and remain vigilant.
