I have never heard of the Alaskan Bermuda Triangle, nor of a legend about Ottermen, who's myth seems to have a bit of werewolf mixed into it.
A small critique: several places it seemed like there were odd word choices or just missing words–curious if this is being translated from what I assume is Portuguese? The article was still understandable, I was just curious :D.
Thanks again for writing about this - upvoted!
