Scientists warn that warming seas and fewer prey are forcing whales and dolphins into unfamiliar and dangerous waters.

Whales and dolphins, once predictable navigators of ocean currents and feeding grounds, are now being pushed off course by climate change. Rising sea temperatures, collapsing prey populations, and shifting habitats are scrambling the ancient migration routes these marine mammals have followed for millennia. Researchers say the result is more whales showing up in unexpected locations, thinner bodies after failed feedings, and greater risk of getting tangled in fishing gear or struck by ships. The marine world’s great travelers may be facing their most perilous journey yet.
