Mystery gray whale sighted again off Spain coast

The second sighting, made 23 days and 3000km after the first, has continued to perplex whale experts.
Gray whales were thought to be extinct across the Atlantic Ocean, so the appearance of an individual within the Mediterranean Sea was a major surprise.
Now it is not clear where the whale is heading or why.
Once, three major populations of gray (also spelt grey) whale existed: in the western and eastern North Pacific Ocean, and in the North Atlantic.
However, the North Atlantic population of gray whale became extinct sometime in the 17th or 18th Century, for reasons that are not clear.
No sightings of the species had been made in the Atlantic Ocean since.
That was until a single individual gray whale was sighted off the coast of Herzliya Marina, Israel on 9 May this year.
That sighting excited and bemused experts: it could either mean that the gray whale had recolonised the Atlantic Ocean, or that a single gray whale had shattered the record for the longest known migration by the species, which usually make a round trip of 15-20,000km each year.
