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.
