**Scientists link remarkable migration to potential climate change impacts**
In a remarkable discovery, a humpback whale has completed one of the longest and most unusual migrations ever documented, according to scientists who suggest climate change could be at play. Initially spotted off Colombia's Pacific coast in 2017, the whale resurfaced years later near the Indian Ocean's Zanzibar, covering a staggering distance of at least 13,000 kilometers.
Experts believe that this magnificent journey might be a response to climate change affecting food supplies or potentially a search for a mate. Ekaterina Kalashnikova from the Tanzania Cetaceans Program described the feat as "truly impressive and unusual even for this highly migratory species." A photograph captured in 2022 shows the same whale near Zanzibar.
Dr. Kalashnikova pointed out that the journey could represent the longest migration ever recorded for a humpback whale. These whales, which inhabit all oceans, undertake annual migrations from warmer breeding zones to nutrient-rich cooler waters. However, this male's journey appears even more extraordinary, connecting two distant breeding locations.
One hypothesis suggests that climate change may be altering the availability of krill, the primary food source for humpback whales, compelling them to travel further in search of sustenance. Alternatively, it reflects a broader exploration of new breeding grounds, thanks to ongoing conservation efforts that are allowing whale populations to recover.
Though the precise motivations remain unknown, Dr. Kalashnikova acknowledges that global climatic shifts, more frequent extreme environmental events, and evolutionary factors could all play a role. This whale was first photographed with a group of humpbacks in 2013 off Colombia's Pacific coast, reidentified in 2017 in the same region, and then spotted near Zanzibar in 2022.
The sightings represent a minimum great-circle distance of 13,046 kilometers, although the actual distance trekked by the whale is likely much longer due to the curvature of the Earth, making the great-circle distance an essential metric in mapping such extensive journeys.
These findings are part of a larger research effort utilizing a citizen science initiative through the website happywhale.com, which compiles photos reported by researchers, whale enthusiasts, and the public. Using artificial intelligence, the program analyzes the unique patterns on humpback whale tails, charting their global movements. The study is published in the journal Royal Society Open Science and illuminates the incredible capabilities of these marine giants amid changing environmental conditions.
