A dead 15-foot whale washed up on a Long Island beach over the weekend, officials say.
The adult female pilot whale was found at about 2 p.m. Sunday east of Coopers Beach in Southampton, officials from the Riverhead Foundation for Marine Research and Preservation say.
A necropsy found no signs of trauma; a cause of death was still being determined.
Rob DiGiovanni, director and senior biologist at the Riverhead Foundation, said it's not abnormal for a pilot whale to be found on the beach but it's not a frequent occurrence.
