Acocil (Cambarellus montezumae)
The acocil is a type of crawfish. The name comes from the Nahuatl cuitzilli, meaning “crooked one of the water.” It can be found in natural and artificial waterways, such as those of Xochimilco. It was commonly eaten by Pre-Columbian mexicans, either boiled or baked and eaten in tacos.
