A grey whale has been spotted off the coast of Israel, in what is thought to be the first time the giant mammal has been seen outside the Pacific in several hundred years.

The whale, which was first sighted off Herzliya in central Israel on Saturday, is believed to have travelled thousands of miles from the north Pacific after losing its way in search of food.

“It’s an unbelievable event which has been described as one of the most important whale sightings ever,” said Dr Aviad Scheinin, chairman of the Israel Marine Mammal Research and Assistance Center which identified the creature.
