"A humpback whale has made one of the longest and most unusual migrations ever recorded, possibly driven by climate change, scientists say.

It was seen in the Pacific Ocean off Colombia in 2017, then popped up several years later near Zanzibar in the Indian Ocean - a distance of at least 13,000 km.

The experts think this epic journey might be down to climate change depleting food stocks or perhaps an odyssey to find a mate.

Ekaterina Kalashnikova of the Tanzania Cetaceans Program said the feat was "truly impressive and unusual even for this highly migratory species"."
