Ahuizotl

The Ahuizotl is a fearsome aquatic creature from Aztec mythology, described as a dog-like or otter-like beast covered in slick fur, with a hand at the tip of its long tail used to snatch victims and drag them underwater. In Nahua tradition it lurked in lakes and rivers of central Mexico, particularly the lake system near Tenochtitlan, luring people with cries resembling a crying infant before pulling them under; it was believed to eat the eyes, teeth, and nails of its victims, whose bodies would later resurface. The creature was closely tied to Tlaloc's watery domain and is documented in the Florentine Codex, the vast Nahua-Spanish encyclopedia compiled by Bernardino de Sahagún and completed around 1577, reflecting real fears about drowning in the region's canals and lakes. The name was famously borrowed by the Aztec ruler Ahuitzotl. Modern scholars view the Ahuizotl as a mythic personification of the genuine dangers of the lake system, an explanatory tale for drownings, later reinterpreted in folklore and popular culture across Mexico.
