(CNN)When local fishermen were walking through a mangrove forest in Brazil, they came across something that shouldn’t be there: the carcass of a humpback whale.
The baby whale was likely lost at sea and died of starvation or some other unknown cause, according to nonprofit research group Bicho D’agua.
The tides washed the whale’s body to shore at Araruna Beach in the city of Soure, said Bicho D’agua oceanographer Maura Sousa. It’s located on the island of Marajó, which sits at the mouth of the Amazon River.
