The humpback whale was found Tuesday morning, not far from where a large sperm whale was found about three weeks earlier.
Dolphins known as "false killer whales" beached themselves in Brazil on Sunday, and nobody knows why.
And if so, why? A pod of 61 whales beached themselves at Farewell Spit in New Zealand on Monday. Itâ€™s not clear why whales beach themselves, but suicide is one theory.
