A 26-foot-long humpback whale was found washed ashore in the Amazon river in Brazil and the country’s scientists are stumped about how it got there.For starters, it was found several days after it had died, according to researchers. It was also found metres from the shore. Researchers are baffled about why the animal was swimming so close to shore in the first place.“We’re still not sure how it landed here, but we’re guessing that the creature was floating close to the shore and the tide, which has been pretty considerable over the past few days, picked it up and threw it inland, into the mangrove,” a conservation specialist and project leader from the Bicho D’agua Institute said.Marine biologists believe it’s a 12-month calf and weighs 10 tons. It was found in a jungle undergrowth on the island of Marajo, which sits at the mouth of the Amazon River, about 50 metres from the shore.More odd, however, is that the whale was there in the first place. The scientists who found it say it was more than 6,000 kilometres away from its feeding grounds. This suggests the mammal died and was taken by the very heavy tides in the region.Lastly, biologists think it’s highly unusual for any whales to be in the region of northern Brazil in February. The animals would have all migrated south to Antarctica.Biologists took samples of the carcass to study it more thoroughly. They hope to find out how it died after performing a necropsy. They’ve hypothesized that the calf was separated from its mother and died.
