A sperm whale stranded on Cuttyhunk Island over the weekend, adding to alarming whale death toll since December. Here's what we know.

Dale Lynch, the assistant harbor master on Cuttyhunk, said the whale was found alive on the south side of the island, straight across from the Gay Head Cliffs, by a walker. He, in turn, contacted federal officials and IFAW, and the whale later died.
