A dead male sperm whale has been towed to an offshore dock near the College of the Atlantic in Bar Harbor. The seaside college said the whale, which is more than 40 feet long and 20 to 30 years old, was found floating off of Schoodic Point by a local fisherman. Scientists believe the whale has been dead for about two weeks and drifted inshore with the currents. A necropsy is being planned. Arrangements are being made to have the whale, which may weigh as much as 50 tons, brought to land to preserve the skeleton for study.
