A dead humpback whale calf washed ashore in Cohasset Sunday morning, officials said.

Police responded to the area of 399 Atlantic Ave. at around 11 a.m. and notified New England Aquarium officials, Cohasset police said in a tweet.

“This is a 2-year-old juvenile, approximately 30 to 35 feet long,” aquarium spokesman Tony LaCasse said.

The Center for Coastal Studies in Provincetown confirmed that the whale is the same one that was seen floating near Gloucester Friday evening, according to LaCasse.

Aquarium officials were on the way to the scene to secure the whale around noon but were unable to as of Sunday evening due to “the rolling surf and because the authorizations from the town are not yet in place,” LaCasse said.


“Heavy surf is moving it around in the area where it was found,” LaCasse said. “The Cohasset harbormaster is monitoring the carcass.”

Once aquarium officials secure the body, they will coordinate with town officials to conduct a necropsy to determine the cause of death and arrange for the body’s disposal, LaCasse said.
