PONTE VEDRA BEACH, Fla. (AP) - Wildlife officials say a beached whale in north Florida has to be euthanized.

The whale is either a male pygmy whale or dwarf sperm whale.

It was found Monday and a necropsy is planned. It could give experts more information about why the whale beached itself. Officials say whales and dolphins often beach themselves when they are sick or injured, as they are too weak to survive in the deep waters.
