Went camping for a night out in the remote Amazon jungle, accompanied by local guides. The next morning we were trekking and heard a strange buzzing and hissing sound. It filled the rainforest and sounded like we stumbled into a witches coven or something. There was loud whooping and whistling, but more than anything - this ominous chorus of sustained droning.

Turned out it was a pack of giant Amazon river otters in the water. These guys get as big as 6 ft. The sound was freaky and they were bearing their fangs at us trying to intimidate, swimming in an agitated manner. No doubt they could have ripped us to shreds if they wanted to. We had higher ground and kept our distance. I managed to take a short video.

After a couple minutes they climbed out of the water and galloped into the jungle. And I mean it when I say galloped. We couldn’t believe how fast they could move on land.

I firmly believe that these are the last animals you would want to come face to face with in all of the Amazon. I would rather face a jaguar than a mob of angry giant river otters.
