amazon whale?

A whale has become trapped in the Amazon River, and I have to say, it doesn’t seem like the smartest whale out there. It’s a minke whale, which is one of the smallest breeds of baleen whales, and it has swam over 1,000 miles up the river. Every time the veterinarians and biologists try to catch it, the whale gets excited and swims farther upriver. Not the brightest light bulb!
