The Dobhar-chú, or “water-hound,” is a legendary otter-like animal that supposedly lives in isolated freshwater loughs and rivers in Ireland. Usually described as a half-dog, half-fish hybrid with a long snaking body covered in thick fur, the Dobhar-chú is large and heavyset, but can move very fast both in the water and on land—even, according to one story, being able to keep up with a galloping horse. Sightings of the creature date back several centuries in Ireland, and there are at least two gravestones (including one, in County Leitrim, dating back as far as 1722) of people who were reportedly attacked and killed by a Dobhar-chú.

This reminds me of giant river otters. They live in the Amazon, and they’re about six feet long, hunt in packs, and are freaky as all heck. They are NOT cute. I’m quite certain one would kill you if you did something to upset it.

I just can’t think of any way a mammal from the Amazon could get to Ireland.
