Humpback whale completes epic 13,000 km migration across oceans, driven by climate change?

A humpback whale has stunned scientists by completing one of the longest migrations ever recorded. Starting off the coast of Colombia in 2017, the whale traveled over 13,000 km to appear near Zanzibar in the Indian Ocean years later.

Experts believe climate change may have disrupted food sources, or the whale may have been on a quest to find a mate. This extraordinary journey is being hailed as an "impressive and unusual" feat for the highly migratory species, according to experts. Watch the video to know more.
