Acocil is a species of crayfish native to Mexico, Cambarellus montezumae. The name acocil comes from the Nahuatl cuitzilli, meaning "crooked one of the water" or "squirms in the water". It is a traditional foodstuff of the Pre-Columbian Mexicans, who boiled or baked the animal, and ate it in tacos. It is found across a broad section of Mexico, "from Lake Chapala in Jalisco to the crater lakes of Puebla", and so is listed as Least Concern on the IUCN Red List.
