The ahuizotl (from the Classical Nahuatl: āhuitzotl for "spiny aquatic thing", a.k.a. "water dog") is a legendary creature in Aztec mythology. It is said to lure people to their deaths. The creature was taken as a mascot by the ruler of the same name, and was said to be a "friend of the rain gods".The conquistador Hernán Cortés once reported to the King of Castile that one of his men had been killed by an ahuizotl.
The Dobhar-chú (Irish pronunciation: [ˈd̪ˠaɾˠxuː], lit. "water dog" or "water hound") or King Otter is a creature of Irish folklore. It resembles both a dog and an otter, though it sometimes is described as half dog, half fish. It lives in water and has fur with protective properties.
