Giant otters can defeat crocodiles

Witch coven exactly, that's genuinely spooky

All otters are assholes regardless of their size. There was a case a couple years ago in Montana of a woman being mauled by river otters. They damn near ripped her face off and tried to drown her. And these weren't even the roided out Amazonian otters. Just normal river otters.
NSFW on that link. There's your warning.
- Have you met humans?
  They are right to treat all those bastards as enemies of their people.
- Now I want to see the poll on Americans who could win a bare knuckle fight with river otters.
  For context, the Northern River Otter in Montana weighs around 20 pounds and measures close to 47 inches long.

That bottom one looks just like the sort of 50 year-old skinhead that turns around to look at you when you enter a pub at lunchtime.

Seen those, they are damn massive. Will have to dig to find all movies and pics

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.

- That does look genuinely scary. Thanks for sharing the video
- That's amazing, simultaneously cute and terrifying
- That is a wild experience, closely followed by what just happened when my cats heard that video.
- Are all those different noises coming from the otters? That's so scary
  
  Yes all of them lol. It was a quiet hike until that
- Thanks for sharing, that was a cool encounter!

these things will, if turned undead, absolutely annihilate a dwarf fortress

Are the honey badgers of rivers/lakes¿

ROUSes (Rodents of Unusual Size)

Don’t fuck wit mustelids.

My brain tells me these are not real and otters don't get this big, but they definitely exist!
I am actually very surprised that I have never heard of these before. Thank you!
